NAME
App::RegexFileUtils - use regexes with file utils like rm, cp, mv, ln
VERSION
version 0.08
SYNOPSIS
Remove all files with a .bak extension:
% rerm '/\.bak$/'
Change the extension of all files from .jpeg or .JPG (any case) to .jpg
% remv '/\.jpe?g$/.jpg/i'
Copy all Perl files to a different directory:
% recp '/\.p[lm]$/' /perl/lib
Create symlinks to .so files so that the symlinks lack a version number
% reln -s '/\.so\..*$/.so/'
DESCRIPTION
This distribution provides a version of rm, cp, mv and ln with a re (as
in regular expression) prefix where the file sources can be specified
as a regular expression, or the file source and destination can be
specified as a regular expression substitution Perl style. The
functionality that this provides can be duplicated with shell syntax
(typically for loops), but I find these scripts require less typing and
work regardless of the shell you are using.
The scripts in this distribution do not remove, copy, move or link
files directly, instead they call the real rm, cp, mv and ln programs
provided by your operating system. You can therefore use any options
that they support, for example the -i option will allow you to
interactively delete files:
% rerm -i '/\.bak$/'
OPTIONS
In addition to any options supported by the underlying operating
system, these scripts will recognize the following options (and NOT
pass them to the underlying system utilities). They are prefixed with
--re so that they do not interfere with any "real" options.
--recmd command
Specifies the command to execute. This is usually determined by Perl's
$0 variable.
--reverbose
Print out the system commands that are actually executed.
--reall
Include even hidden dot files, like .profile and .login.
METHODS
These commands can also be invoked from your Perl script, using this
module:
main
App::RegexFileUtils->main( $program, @arguments )
For example:
use App::RegexFileUtils;
App::RegexFileUtils->main( 'rm', '/\.bak$/' );
CAVEATS
You will need to enclose many regular expressions in single quotes ''
on the command line as many regular expression characters have special
meanings in shells.
The underlying fileutils command (rm, cp, ln, etc) will be called for
each file operated on, which may be slow if many files match the
regular expression provided.
This was written a long time ago and the code isn't very modern.
Directories with a training slash may be ambiguous with a regex, so if
you want to use a path as a destination instead of a regex, be sure you
do NOT include the trailing slash. That is:
# use this:
% recp /^foo/ /usr/bin
# NOT this:
% recp /^foo/ /usr/bin/
BUNDLED FILES
This distribution comes bundled with cp, ln, rm, touch from the Perl
Power Tools <https://metacpan.org/release/ppt> project. These are only
used if the operating system does not provide these commands. This is
normally only the case on Windows. They are individually licensed
separately.
