PROGRAM:
NAME
pwget - Perl Web URL fetch program
SYNOPSIS
pwget http://example.com/ [URL ...]
pwget --config $HOME/config/pwget.conf --Tag linux --Tag emacs ..
pwget --verbose --overwrite http://example.com/
pwget --verbose --overwrite --Output ~/dir/ http://example.com/
pwget --new --overwrite http://example.com/package-1.1.tar.gz
DESCRIPTION
Automate periodic downloads of files and packages.
If you retrieve latest versions of certain program blocks periodically, this is the Perl
script for you. Run from cron job or once a week to upload newest versions of files around
the net. Note:
Wget and this program
At this point you may wonder, where would you need this perl program when wget(1)
C-program has been the standard for ages. Well, 1) Perl is cross platform and more easily
extendable 2) You can record file download criterias to a configuration file and use perl
regular epxressions to select downloads 3) the program can anlyze web-pages and "search"
for the download only links as instructed 4) last but not least, it can track newest
packages whose name has changed since last downlaod. There are heuristics to determine the
newest file or package according to file name skeleton defined in configuration.
This program does not replace pwget(1) because it does not offer as many options as wget,
like recursive downloads and date comparing. Use wget for ad hoc downloads and this
utility for files that change (new releases of archives) or which you monitor
periodically.
Short introduction
This small utility makes it possible to keep a list of URLs in a configuration file and
periodically retrieve those pages or files with simple commands. This utility is best
suited for small batch jobs to download e.g. most recent versions of software files. If
you use an URL that is already on disk, be sure to supply option --overwrite to allow
overwriting existing files.
While you can run this program from command line to retrieve individual files, program has
been designed to use separate configuration file via --config option. In the configuration
file you can control the downloading with separate directives like "save:" which tells to
save the file under different name. The simplest way to retrieve the latest version of
apackage from a FTP site is:
pwget --new --overwite --verbose
http://www.example.com/package-1.00.tar.gz
Do not worry about the filename "package-1.00.tar.gz". The latest version, say,
"package-3.08.tar.gz" will be retrieved. The option --new instructs to find newer version
than the provided URL.
If the URL ends to slash, then directory list at the remote machine is stored to file:
!path!000root-file
The content of this file can be either index.html or the directory listing depending on
the used http or ftp protocol.
OPTIONS
-A, --regexp-content REGEXP
Analyze the content of the file and match REGEXP. Only if the regexp matches the file
content, then download file. This option will make downloads slow, because the file is
read into memory as a single line and then a match is searched against the content.
For example to download Emacs lisp file (.el) written by Mr. Foo in case insensitive
manner:
pwget -v -R '\.el$' -A "(?i)Author: Mr. Foo"
http://www.emacswiki.org/elisp/index.html
-C, --create-paths
Create paths that do not exist in "lcd:" directives.
By default, any LCD directive to non-existing directory will interrupt program. With
this option, local directories are created as needed making it possible to re-create
the exact structure as it is in configuration file.
-c, --config FILE
This option can be given multiple times. All configurations are read.
Read URLs from configuration file. If no configuration file is given, file pointed by
environment variable is read. See ENVIRONMENT.
The configuration file layout is envlained in section CONFIGURATION FILE
--chdir DIRECTORY
Do a chdir() to DIRECTORY before any URL download starts. This is like doing:
cd DIRECTORY
pwget http://example.com/index.html
-d, --debug [LEVEL]
Turn on debug with positive LEVEL number. Zero means no debug. This option turns on
--verbose too.
-e, --extract
Unpack any files after retrieving them. The command to unpack typical archive files
are defined in a program. Make sure these programs are along path. Win32 users are
encouraged to install the Cygwin utilities where these programs come standard. Refer
to section SEE ALSO.
.tar => tar
.tgz => tar + gzip
.gz => gzip
.bz2 => bzip2
.zip => unzip
-F, --firewall FIREWALL
Use FIREWALL when accessing files via ftp:// protocol.
-h, --help
Print help page in text.
--help-html
Print help page in HTML.
--help-man
Print help page in Unix manual page format. You want to feed this output to c<nroff
-man> in order to read it.
Print help page.
-m, --mirror SITE
If URL points to Sourcefoge download area, use mirror SITE for downloading.
Alternatively the full full URL can include the mirror information. And example:
--mirror kent http://downloads.sourceforge.net/foo/foo-1.0.0.tar.gz
-n, --new
Get newest file. This applies to datafiles, which do not have extension .asp or .html.
When new releases are announced, the version number in filename usually tells which is
the current one so getting harcoded file with:
pwget -o -v http://example.com/dir/program-1.3.tar.gz
is not usually practical from automation point of view. Adding --new option to the
command line causes double pass: a) the whole http://example.com/dir/ is examined for
all files and b) files matching approximately filename program-1.3.tar.gz are
examined, heuristically sorted and file with latest version number is retrieved.
--no-lcd
Ignore "lcd:" directives in configuration file.
In the configuration file, any "lcd:" directives are obeyed as they are seen. But if
you do want to retrieve URL to your current directory, be sure to supply this option.
Otherwise the file will end to the directory pointer by "lcd:".
--no-save
Ignore "save:" directives in configuration file. If the URLs have "save:" options,
they are ignored during fetch. You usually want to combine --no-lcd with --no-save
--no-extract
Ignore "x:" directives in configuration file.
-O, --output DIR
Before retrieving any files, chdir to DIR.
-o, --overwrite
Allow overwriting existing files when retrieving URLs. Combine this with
--skip-version if you periodically update files.
--proxy PROXY
Use PROXY server for HTTP. (See --Firewall for FTP.). The port number is optional in
the call:
--proxy http://example.com.proxy.com
--proxy example.com.proxy.com:8080
-p, --prefix PREFIX
Add PREFIX to all retrieved files.
-P, --postfix POSTFIX
Add POSTFIX to all retrieved files.
-D, --prefix-date
Add iso8601 ":YYYY-MM-DD" prefix to all retrived files. This is added before possible
--prefix-www or --prefix.
-W, --prefix-www
Usually the files are stored with the same name as in the URL dir, but if you retrieve
files that have identical names you can store each page separately so that the file
name is prefixed by the site name.
http://example.com/page.html --> example.com::page.html
http://example2.com/page.html --> example2.com::page.html
-r, --regexp REGEXP
Retrieve file matching at the destination URL site. This is like "Connect to the URL
and get all files matching REGEXP". Here all gzip compressed files are found form HTTP
server directory:
pwget -v -R "\.gz" http://example.com/archive/
-R, --config-regexp REGEXP
Retrieve URLs matching REGEXP from configuration file. This cancels --Tag options in
the command line.
-s, --selftest
Run some internal tests. For maintainer or developer only.
--sleep SECONDS
Sleep SECONDS before next URL request. When using regexp based downlaods that may
return many hits, some sites disallow successive requests in within short period of
time. This options makes program sleep for number of SECONDS between retrievals to
overcome 'Service unavailable'.
--stdout
Retrieve URL and write to stdout.
--skip-version
Do not download files that have version number and which already exists on disk.
Suppose you have these files and you use option --skip-version:
package.tar.gz
file-1.1.tar.gz
Only file.txt is retrieved, because file-1.1.tar.gz contains version number and the
file has not changed since last retrieval. The idea is, that in every release the
number in in distribution increases, but there may be distributions which do not
contain version number. In regular intervals you may want to load those packages
again, but skip versioned files. In short: This option does not make much sense
without additional option --new
If you want to reload versioned file again, add option --overwrite.
-t, --test, --dry-run
Run in test mode.
-T, --tag NAME [NAME] ...
Search tag NAME from the config file and download only entries defined under that tag.
Refer to --config FILE option description. You can give Multiple --Tag switches.
Combining this option with --regexp does not make sense and the concequencies are
undefined.
-v, --verbose [NUMBER]
Print verbose messages.
-V, --version
Print version information.
EXAMPLES
Get files from site:
pwget http://www.example.com/dir/package.tar.gz ..
Display copyright file for package GNU make from Debian pages:
pwget --stdout --regexp 'copyright$' http://packages.debian.org/unstable/make
Get all mailing list archive files that match "gz":
pwget --regexp gz http://example.com/mailing-list/archive/download/
Read a directory and store it to filename YYYY-MM-DD::!dir!000root-file.
pwget --prefix-date --overwrite --verbose http://www.example.com/dir/
To update newest version of the package, but only if there is none at disk already. The
--new option instructs to find newer packages and the filename is only used as a skeleton
for files to look for:
pwget --overwrite --skip-version --new --verbose
ftp://ftp.example.com/dir/packet-1.23.tar.gz
To overwrite file and add a date prefix to the file name:
pwget --prefix-date --overwrite --verbose
http://www.example.com/file.pl
--> YYYY-MM-DD::file.pl
To add date and WWW site prefix to the filenames:
pwget --prefix-date --prefix-www --overwrite --verbose
http://www.example.com/file.pl
--> YYYY-MM-DD::www.example.com::file.pl
Get all updated files under cnfiguration file's tag updates:
pwget --verbose --overwrite --skip-version --new --Tag updates
pwget -v -o -s -n -T updates
Get files as they read in the configuration file to the current directory, ignoring any
"lcd:" and "save:" directives:
pwget --config $HOME/config/pwget.conf /
--no-lcd --no-save --overwrite --verbose
http://www.example.com/file.pl
To check configuration file, run the program with non-matching regexp and it parses the
file and checks the "lcd:" directives on the way:
pwget -v -r dummy-regexp
-->
pwget.DirectiveLcd: LCD [$EUSR/directory ...]
is not a directory at /users/foo/bin/pwget line 889.
CONFIGURATION FILE
Comments
The configuration file is NOT Perl code. Comments start with hash character (#).
Variables
At this point, variable expansions happen only in lcd:. Do not try to use them anywhere
else, like in URLs.
Path variables for lcd: are defined using following notation, spaces are not allowed in
VALUE part (no directory names with spaces). Varaible names are case sensitive. Variables
substitute environment variabales with the same name. Environment variables are
immediately available.
VARIABLE = /home/my/dir # define variable
VARIABLE = $dir/some/file # Use previously defined variable
FTP = $HOME/ftp # Use environment variable
The right hand can refer to previously defined variables or existing environment
variables. Repeat, this is not Perl code although it may look like one, but just an
allowed syntax in the configuration file. Notice that there is dollar to the right hand>
when variable is referred, but no dollar to the left hand side when variable is defined.
Here is example of a possible configuration file contant. The tags are hierarchically
ordered without a limit.
Warning: remember to use different variables names in separate include files. All
variables are global.
Include files
It is possible to include more configuration files with statement
INCLUDE <path-to-file-name>
Variable expansions are possible in the file name. There is no limit how many or how deep
include structure is used. Every file is included only once, so it is safe to to have
multiple includes to the same file. Every include is read, so put the most importat
override includes last:
INCLUDE <etc/pwget.conf> # Global
INCLUDE <$HOME/config/pwget.conf> # HOME overrides it
A special "THIS" tag means relative path of the current include file, which makes it
possible to include several files form the same directory where a initial include file
resides
# Start of config at /etc/pwget.conf
# THIS = /etc, current location
include <THIS/pwget-others.conf>
# Refers to directory where current user is: the pwd
include <pwget-others.conf>
# end
Configuraton file example
The configuration file can contain many <directoves:>, where each directive end to a
colon. The usage of each directory is best explained by examining the configuration file
below and reading the commentary near each directive.
# $HOME/config/pwget.conf F- Perl pwget configuration file
ROOT = $HOME # define variables
CONF = $HOME/config
UPDATE = $ROOT/updates
DOWNL = $ROOT/download
# Include more configuration files. It is possible to
# split a huge file in pieces and have "linux",
# "win32", "debian", "emacs" configurations in separate
# and manageable files.
INCLUDE <$CONF/pwget-other.conf>
INCLUDE <$CONF/pwget-more.conf>
tag1: local-copies tag1: local # multiple names to this category

# End of configuration file pwget.conf
LIST OF DIRECTIVES IN CONFIGURATION FILE
All the directives must in the same line where the URL is. The programs scans lines and
determines all options given in line for the URL. Directives can be overridden by command
line options.
cnv:CONVERSION
Currently only conv:text is available.
Convert downloaded page to text. This option always needs either save: or rename:,
because only those directives change filename. Here is an example:
http://example.com/dir/file.html cnv:text save:file.txt
http://example.com/dir/ pregexp:\.html cnv:text rename:s/html/txt/
A text: shorthand directive can be used instead of cnv:text.
cregexp:REGEXP
Download file only if the content matches REGEXP. This is same as option
--Regexp-content. In this example directory listing Emacs lisp packages (.el) are
downloaded but only if their content indicates that the Author is Mr. Foo:
http://example.com/index.html cregexp:(?i)author:.*Foo pregexp:\.el$
lcd:DIRECTORY
Set local download directory to DIRECTORY (chdir to it). Any environment variables are
substituted in path name. If this tag is found, it replaces setting of --Output. If
path is not a directory, terminate with error. See also --Create-paths and --no-lcd.
login:LOGIN-NAME
Ftp login name. Default value is "anonymous".
mirror:SITE
This is relevant to Sourceforge only which does not allow direct downloads with links.
Visit project's Sourceforge homepage and see which mirrors are available for
downloading.
An example:
http://sourceforge.net/projects/austrumi/files/austrumi/austrumi-1.8.5/austrumi-1.8.5.iso/download new: mirror:kent
new:
Get newest file. This variable is reset to the value of --new after the line has been
processed. Newest means, that an "ls" command is run in the ftp, and something
equivalent in HTTP "ftp directories", and any files that resemble the filename is
examined, sorted and heurestically determined according to version number of file
which one is the latest. For example files that have version information in YYYYMMDD
format will most likely to be retrieved right.
Time stamps of the files are not checked.
The only requirement is that filename "must" follow the universal version numbering
standard:
FILE-VERSION.extension # de facto VERSION is defined as [\d.]+
file-19990101.tar.gz # ok
file-1999.0101.tar.gz # ok
file-1.2.3.5.tar.gz # ok
file1234.txt # not recognized. Must have "-"
file-0.23d.tar.gz # warning, letters are problematic
Files that have some alphabetic version indicator at the end of VERSION may not be
handled correctly. Contact the developer and inform him about the de facto standard so
that files can be retrieved more intelligently.
NOTE: In order the new: directive to know what kind of files to look for, it needs a
file tamplate. You can use a direct link to some filename. Here the location
"http://www.example.com/downloads" is examined and the filename template used is took
as "file-1.1.tar.gz" to search for files that might be newer, like
"file-9.1.10.tar.gz":
http://www.example.com/downloads/file-1.1.tar.gz new:
If the filename appeard in a named page, use directive file: for template. In this
case the "download.html" page is examined for files looking like "file.*tar.gz" and
the latest is searched:
http://www.example.com/project/download.html file:file-1.1.tar.gz new:
overwrite: o:
Same as turning on --overwrite
page:
Read web page and apply commands to it. An example: contact the root page and save it:
http://example.com/~foo page: save:foo-homepage.html
In order to find the correct information from the page, other directives are usually
supplied to guide the searching.
1) Adding directive "pregexp:ARCHIVE-REGEXP" matches the A HREF links in the page.
2) Adding directive new: instructs to find newer VERSIONS of the file.
3) Adding directive "file:DOWNLOAD-FILE" tells what template to use to construct the
downloadable file name. This is needed for the "new:" directive.
4) A directive "vregexp:VERSION-REGEXP" matches the exact location in the page from
where the version information is extracted. The default regexp looks for line that
says "The latest version ... is ... N.N". The regexp must return submatch 2 for the
version number.
AN EXAMPLE
Search for newer files from a HTTP directory listing. Examine page
http://www.example.com/download/dir for model "package-1.1.tar.gz" and find a newer
file. E.g. "package-4.7.tar.gz" would be downloaded.
http://www.example.com/download/dir/package-1.1.tar.gz new:
AN EXAMPLE
Search for newer files from the content of the page. The directive file: acts as a
model for filenames to pay attention to.
http://www.example.com/project/download.html new: pregexp:tar.gz file:package-1.1.tar.gz
AN EXAMPLE
Use directive rename: to change the filename before soring it on disk. Here, the
version number is attached to the actila filename:
file.txt-1.1
file.txt-1.2
The directived needed would be as follows; entries have been broken to separate lines
for legibility:
http://example.com/files/
pregexp:\.el-\d
vregexp:(file.el-([\d.]+))
file:file.el-1.1
new:
rename:s/-[\d.]+//
This effectively reads: "See if there is new version of something that looks like
file.el-1.1 and save it under name file.el by deleting the extra version number at the
end of original filename".
AN EXAMPLE
Contact absolute page: at http://www.example.com/package.html and search A HREF urls
in the page that match pregexp:. In addition, do another scan and search the version
number in the page from thw position that match vregexp: (submatch 2).
After all the pieces have been found, use template file: to make the retrievable file
using the version number found from vregexp:. The actual download location is
combination of page: and A HREF pregexp: location.
The directived needed would be as follows; entries have been broken to separate lines
for legibility:
http://www.example.com/~foo/package.html
page:
pregexp: package.tar.gz
vregexp: ((?i)latest.*?version.*?\b([\d][\d.]+).*)
file: package-1.3.tar.gz
new:
x:
An example of web page where the above would apply:
<HTML>
<BODY>
The latest version of package is <B>2.4.1</B> It can be
downloaded in several forms:
<A HREF="download/files/package.tar.gz">Tar file</A>
<A HREF="download/files/package.zip">ZIP file
</BODY>
</HTML>
For this example, assume that "package.tar.gz" is a symbolic link pointing to the
latest release file "package-2.4.1.tar.gz". Thus the actual download location would
have been "http://www.example.com/~foo/download/files/package-2.4.1.tar.gz".
Why not simply download "package.tar.gz"? Because then the program can't decide if the
version at the page is newer than one stored on disk from the previous download. With
version numbers in the file names, the comparison is possible.
page:find
FIXME: This opton is obsolete. do not use.
THIS IS FOR HTTP only. Use Use directive regexp: for FTP protocls.
This is a more general instruction than the page: and vregexp: explained above.
Instruct to download every URL on HTML page matching pregexp:RE. In typical situation
the page maintainer lists his software in the development page. This example would
download every tar.gz file in the page. Note, that the REGEXP is matched against the A
HREF link content, not the actual text that is displayed on the page:
http://www.example.com/index.html page:find pregexp:\.tar.gz$
You can also use additional regexp-no: directive if you want to exclude files after
the pregexp: has matched a link.
http://www.example.com/index.html page:find pregexp:\.tar.gz$ regexp-no:desktop
pass:PASSWORD
For FTP logins. Default value is "nobody@example.com".
pregexp:RE
Search A HREF links in page matching a regular expression. The regular expression must
be a single word with no whitespace. This is incorrect:
pregexp:(this regexp )
It must be written as:
pregexp:(this\s+regexp\s)
print:MESSAGE
Print associated message to user requesting matching tag name. This directive must in
separate line inside tag.
tag1: linux
print: this download site moved 2002-02-02, check your bookmarks.
http://new.site.com/dir/file-1.1.tar.gz new:
The "print:" directive for tag is shown only if user turns on --verbose mode:
pwget -v -T linux
rename:PERL-CODE
Rename each file using PERL-CODE. The PERL-CODE must be full perl program with no
spaces anywhere. Following variables are available during the eval() of code:
$ARG = current file name
$url = complete url for the file
The code must return $ARG which is used for file name
For example, if page contains links to .html files that are in fact text files,
following statement would change the file extensions:
http://example.com/dir/ page:find pregexp:\.html rename:s/html/txt/
You can also call function "MonthToNumber($string)" if the filename contains written
month name, like <2005-February.mbox>.The function will convert the name into number.
Many mailing list archives can be donwloaded cleanly this way.
# This will download SA-Exim Mailing list archives:
http://lists.merlins.org/archives/sa-exim/ pregexp:\.txt$ rename:$ARG=MonthToNumber($ARG)
Here is a more complicated example:
http://www.contactor.se/~dast/svnusers/mbox.cgi pregexp:mbox.*\d$ rename:my($y,$m)=($url=~/year=(\d+).*month=(\d+)/);$ARG="$y-$m.mbox"
Let's break that one apart. You may spend some time with this example since the
possiblilities are limitless.
1. Connect to page
http://www.contactor.se/~dast/svnusers/mbox.cgi
2. Search page for URLs matching regexp 'mbox.*\d$'. A
found link could match hrefs like this:
http://svn.haxx.se/users/mbox.cgi?year=2004&month=12
3. The found link is put to $ARG (same as $_), which can be used
to extract suitable mailbox name with a perl code that is
evaluated. The resulting name must apear in $ARG. Thus the code
effectively extract two items from the link to form a mailbox
name:
my ($y, $m) = ( $url =~ /year=(\d+).*month=(\d+)/ )
$ARG = "$y-$m.mbox"
=> 2004-12.mbox
Just remember, that the perl code that follows "rename:" directive must must not
contain any spaces. It all must be readable as one string.
regexp:REGEXP
Get all files in ftp directory matching regexp. Directive save: is ignored.
regexp-no:REGEXP
After the "regexp:" directive has matched, exclude files that match directive regexp-
no:
Regexp:REGEXP
This option is for interactive use. Retrieve all files from HTTP or FTP site which
match REGEXP.
save:LOCAL-FILE-NAME
Save file under this name to local disk.
tagN:NAME
Downloads can be grouped under "tagN" so that e.g. option --Tag1 would start
downloading files from that point on until next "tag1" is found. There are currently
unlimited number of tag levels: tag1, tag2 and tag3, so that you can arrange your
downlods hierarchially in the configuration file. For example to download all Linux
files rhat you monitor, you would give option --Tag linux. To download only the NT
Emacs latest binary, you would give option --Tag emacs-nt. Notice that you do not give
the "level" in the option, program will find it out from the configuration file after
the tag name matches.
The downloading stops at next tag of the "same level". That is, tag2 stops only at
next tag2, or when upper level tag is found (tag1) or or until end of file.
tag1: linux # All Linux downlods under this category
tag2: sunsite tag2: another-name-for-this-spot
# List of files to download from here
tag2: ftp.funet.fi
# List of files to download from here
tag1: emacs-binary
tag2: emacs-nt
tag2: xemacs-nt
tag2: emacs
tag2: xemacs
x: Extract (unpack) file after download. See also option --unpack and --no-extract The
archive file, say .tar.gz will be extracted the file in current download location.
(see directive lcd:)
The unpack procedure checks the contents of the archive to see if the package is
correctly formed. The de facto archive format is
package-N.NN.tar.gz
In the archive, all files are supposed to be stored under the proper subdirectory with
version information:
package-N.NN/doc/README
package-N.NN/doc/INSTALL
package-N.NN/src/Makefile
package-N.NN/src/some-code.java
"IMPORTANT:" If the archive does not have a subdirectory for all files, a subdirectory
is created and all items are unpacked under it. The defualt subdirectory name in
constructed from the archive name with currect date stamp in format:
package-YYYY.MMDD
If the archive name contains something that looks like a version number, the created
directory will be constructed from it, instead of current date.
package-1.43.tar.gz => package-1.43
xx: Like directive x: but extract the archive "as is", without checking content of the
archive. If you know that it is ok for the archive not to include any subdirectories,
use this option to suppress creation of an artificial root package-YYYY.MMDD.
xopt:rm
This options tells to remove any previous unpack directory.
Sometimes the files in the archive are all read-only and unpacking the archive second
time, after some period of time, would display
tar: package-3.9.5/.cvsignore: Could not create file:
Permission denied
tar: package-3.9.5/BUGS: Could not create file:
Permission denied
This is not a serious error, because the archive was already on disk and tar did not
overwrite previous files. It might be good to inform the archive maintainer, that the
files have wrong permissions. It is customary to expect that distributed packages have
writable flag set for all files.
ERRORS
Here is list of possible error messages and how to deal with them. Turning on --debug
will help to understand how program has interpreted the configuration file or command line
options. Pay close attention to the generated output, because it may reveal that a regexp
for a site is too lose or too tight.
ERROR {URL-HERE} Bad file descriptor
This is "file not found error". You have written the filename incorrectly. Double
check the configuration file's line.
Use pwget online using onworks.net services
