NAME

rpl — replace strings in files

SYNOPSIS

rpl [-LhiwbqvsRepfdt] [-xSUFFIX] ⟨old_string⟩ ⟨new_string⟩ ⟨target_file ...⟩

DESCRIPTION

Basic usage is to specify two strings and one or more filenames or directories on the
command line. The first string is the string to replace, and the second string is the
replacement string.

-h, --help
A short help text.

-L, --license
Show the license and exit.

-xSUFFIX
Search only files ending with SUFFIX, e.g. “.txt”. May be specified multiple
times.

-i, --ignore-case
Ignore the case of old_string.

-w, --whole-words
Make old_string match only on word boundaries.

-b, --backup
Move the original files to filename~ before replacing them.

-q, --quiet
Quiet mode.

-v, --verbose
Verbose mode.

-s, --dry-run
Simulation mode, no files are changed.

-R, --recursive
Recurse into subdirectories.

-e, --escape
Expand escape sequences in old_string and new_string. Examples of escape sequences
are ‘\n’ (new-line), ‘\t’ (tab), ‘\x42’ (hexadecimal number 42), ‘\033’ (octal
number 033).

-p, --prompt
Prompt for confirmation before replacing each file.

-f, --force
Ignore errors when trying to restore permissions and file ownership.

-d, --keep-times
Keep modification times when replacing files.

-t, --use-tmpdir
Use a temporary directory for storing temporary files, usually the value of the
environment variable TMPDIR. The default is to put temporary files in the same
directory as the file being modified.

-a, --all
Do not ignore files and directories starting with .

IMPLEMENTATION NOTES

An effort has been made to make the program behave as much as the original rpl as necessary.
Where it has been possible to make improvements, improvements have been made. This
implementation lacks many of the bugs in the original.

EXAMPLES

Replace all occurences of “F” (on word boundaries) with “A” in all text files under the
grades/ directory:
$ rpl -Rwd -x'.txt' 'F' 'A' grades/
