file::remove
File::Remove(3) User Contributed Perl Documentation File::Remove(3)
NAME
File::Remove - Remove files and directories
SYNOPSIS
use File::Remove 'remove';
# removes (without recursion) several files
remove( '*.c', '*.pl' );
# removes (with recursion) several directories
remove( 1, qw{directory1 directory2} );
# removes (with recursion) several files and directories
remove( 1, qw{file1 file2 directory1 *~} );
# trashes (with support for undeleting later) several files
trash( '*~' );
DESCRIPTION
File::Remove::remove removes files and directories. It acts like /bin/rm, for the most part. Although "unlink" can be given a list of
files, it will not remove directories; this module remedies that. It also accepts wildcards, * and ?, as arguments for filenames.
File::Remove::trash accepts the same arguments as remove, with the addition of an optional, infrequently used "other platforms" hashref.
SUBROUTINES
remove
Removes files and directories. Directories are removed recursively like in rm -rf if the first argument is a reference to a scalar that
evaluates to true. If the first arguemnt is a reference to a scalar then it is used as the value of the recursive flag. By default it's
false so only pass 1 to it.
In list context it returns a list of files/directories removed, in scalar context it returns the number of files/directories removed. The
list/number should match what was passed in if everything went well.
rm
Just calls remove. It's there for people who get tired of typing remove.
clear
The "clear" function is a version of "remove" designed for use in test scripts. It takes a list of paths that it will both initially delete
during the current test run, and then further flag for deletion at END-time as a convenience for the next test run.
trash
Removes files and directories, with support for undeleting later. Accepts an optional "other platforms" hashref, passing the remaining
arguments to remove.
Win32
Requires Win32::FileOp.
Installation not actually enforced on Win32 yet, since Win32::FileOp has badly failing dependencies at time of writing.
OS X
Requires Mac::Glue.
Other platforms
The first argument to trash() must be a hashref with two keys, 'rmdir' and 'unlink', each referencing a coderef. The coderefs will be
called with the filenames that are to be deleted.
