DESCRIPTION
The s5 tool eases the creation of presentation slides using the “Simple Standards-based
Slide Show System”. It may be used to create a working copy of a template directory or,
later, to update the working copy after the template has changed over time.
The s5 tool supports the following command-line options:
-d Specify the top-level directory containing the available templates.
-h Display a short help text and exit.
-N No-operation mode; just display the commands without executing them.
-t template
Specify the template within the directory given by the -d option.
-T full
Specify the full path to the template directory instead of the default
/usr/share/s5/s5-blank
-v Verbose operation; display diagnostic information.
The s5 tool supports the following actions:
blank path
Aliases: create, new
Copy the template directory into the directory specified by path, creating it if
necessary.
cksum path
Aliases: check, verify
Verify the checksums recorded for the S5 presentation files in the directory
specified by path. The s5 utility reports both files that have been modified (fail
the checksum check) and files that no longer exist yet have checksums recorded.
help Alias: usage
Display a short help message and exit.
mksum path
Record the template checksums into a file in a directory specified by path. Users
should never really have to execute this by hand, since it is done internally as
part of the blank and update command processing.
update path
Update the S5 presentation files in the directory specified by path with the new
versions in the S5 template directory.
Before updating, the s5 utility verifies the checksums of the files in the path
directory, and terminates if a mismatch is found. After that, s5 checks for any
files that exist in both the new template and in the path directory, but are not
recorded in the checksum file (i.e. have been placed in path by hand after the last
s5 blank or s5 update run) and terminates if any such files differ.
If all these checks are successful, the s5 utility copies the template files over
those in path, overwriting any existing files and retaining any files that do not
exist in the template directory.
THE CONFIGURATION FILE
The s5 utility's operation may be customized by specifying some common parameters in a
configuration file that is read at each invocation. There are two configuration files - the
global /etc/s5.conf and a per-user .s5.conf in the user's home directory. The global file
is read first; the per-user file may override any of its settings.
The configuration file has simple shell-like syntax; its purpose is merely to optionally set
some variables. Lines starting with the “#” character are ignored as comments. The
variables that affect the operation of s5 are:
S5_DIR The top-level directory containing all the templates; overridden by the command-line
-d option. Default: /usr/share/s5
S5_TEMPLATE
The name of the template to use, a subdirectory within S5_DIR; overridden by the
command-line -t option. Default: s5-blank
THE CHECKSUMS FILE
The s5 utility stores the checksums of blank S5 presentations into a file named
s5-checksums.txt into the presentation directory. This is a simple text file with lines
containing of a keyword and values. The keywords that the s5 utility currently generates
and parses are as follows:
CKSUM_CMD checksum-program
The name of the checksum program to use; the default is cksum(1).
CKSUM_ARGS [[argument...]]
The arguments (if any) passed to the checksum program as defined by the CKSUM_CMD
line. The default is an empty string, no arguments passed.
FILE filename
The name of the file that the following CKSUM line refers to.
CKSUM checksum-line-text
The output of the checksum command as specified by CKSUM_CMD and CKSUM_ARGS
conflated into a single line.
EXAMPLES
Start a brand new presentation:
s5 blank ~/txt/openfest/2006/gnupg-pres
cd ~/txt/openfest/2006/gnupg-pres/
mv s5-blank/ gnupg/
Verify if any of the S5 files in the presentation have been modified:
s5 cksum gnupg/
Do the same, but display verbose information about the lines read from the checksums file
and the files verified:
s5 -v cksum gnupg/
Update the S5 presentation files after installing a new system-wide version of the S5
template:
s5 update gnupg/
Store the checksums of the S5 template files (not the real files in the presentation
directory!) into the s5-checksums.txt file in the gnupg/ directory; this is actually
redundant, as it is done as part of the s5 blank invocation:
s5 mksum gnupg/
