NAME

File::Trash::FreeDesktop - Trash files

VERSION

This document describes version 0.18 of File::Trash::FreeDesktop (from Perl distribution File-Trash-FreeDesktop), released on 2015-08-17.

SYNOPSIS

 use File::Trash::FreeDesktop;

 my $trash = File::Trash::FreeDesktop->new;

 # list available (for the running user) trash directories
 my @trashes = $trash->list_trashes;

 # list the content of a trash directory
 my @content = $trash->list_contents("/tmp/.Trash-1000");

 # list the content of all available trash directories
 my @content = $trash->list_contents;

 # trash a file
 $trash->trash("/foo/bar");

 # specify some options when trashing
 $trash->trash({on_not_found=>'ignore'}, "/foo/bar");

 # recover a file from trash (untrash)
 $trash->recover('/foo/bar');

 # untrash a file from a specific trash directory
 $trash->recover('/tmp/file', '/tmp/.Trash-1000');

 # specify some options when untrashing
 $trash->recover({on_not_found=>'ignore', on_target_exists=>'ignore'}, '/path');

 # empty a trash directory
 $trash->empty("$ENV{HOME}/.local/share/Trash");

 # empty all available trashes
 $trash->empty;

DESCRIPTION

This module lets you trash/erase/restore files, also list the contents of trash directories. This module follows the freedesktop.org trash specification [1], with some notes/caveats:

  • For home trash, $HOME/.local/share/Trash is used instead of $HOME/.Trash

    This is what KDE and GNOME use these days.

  • Symlinks are currently not checked

    The spec requires implementation to check whether trash directory is a symlink, and refuse to use it in that case. This module currently does not do said checking.

  • Currently cross-device copying is not implemented/done

    It should not matter though, because trash directories are per-filesystem.

Some other notes:

METHODS

$trash = File::Trash::FreeDesktop->new(%opts)

Constructor.

Currently there are no known options.

$trash->list_trashes() => LIST

List user's existing trash directories on the system.

Return a list of trash directories. Sample output:

 ("/home/mince/.local/share/Trash",
  "/tmp/.Trash-1000")

$trash->list_contents([$trash_dir]) => LIST

List contents of trash director(y|ies).

If $trash_dir is not specified, list contents from all existing trash directories. Die if $trash_dir does not exist or inaccessible or corrupt. Return a list of records like the sample below:

 ({entry=>"file1", path=>"/home/mince/file1", deletion_date=>1342061508,
   trash_dir=>"/home/mince/.local/share/Trash"},
  {entry=>"file1.2", path=>"/home/mince/sub/file1", deletion_date=>1342061580,
   trash_dir=>"/home/mince/.local/share/Trash"},
  {entry=>"dir1", path=>"/tmp/dir1", deletion_date=>1342061510,
   trash_dir=>"/tmp/.Trash-1000"})

$trash->trash([\%opts, ]$file) => STR

Trash a file (move it into trash dir).

Will try to find a trash dir that resides in the same filesystem/device as the file and is writable. $home/.local/share/Trash is tried first, then $device_root/.Trash-$uid, then $device_root/tmp/.Trash-$uid. Will die if no suitable trash dir is found.

Will also die if moving file to trash (currently using rename()) fails.

Upon success, will return the location of the file in the trash dir (e.g. /tmp/.Trash-1000/files/foo).

If first argument is a hashref, it will be accepted as options. Known options:

  • on_not_found => STR (default 'die')

    Specify what to do when the file to be deleted is not found. The default is 'die', but can also be set to 'ignore' and return immediately.

  • suffix => STR

    Pick a suffix. Normally, file will be stored in files/ORIGNAME inside trash directory, or, if that file already exists, in files/ORIGNAME.1, files/ORIGNAME.2, and so on. This setting overrides this behavior and picks files/ORIGNAME.SUFFIX. Can be used to identify and restore particular file later. However, will die if file with that suffix already exists, so be sure to pick a unique suffix.

$trash->recover([\%opts, ]$file[, $trash_dir])

Recover a file from trash.

Unless $trash_dir is specified, will search in all existing user's trash dirs. Will die on errors.

If first argument is a hashref, it will be accepted as options. Known options:

  • on_not_found => STR (default 'die')

    Specify what to do when file is not found in the trash. The default is 'die', but can also be set to 'ignore' and return immediately.

  • on_target_exists => STR (default 'die')

    Specify what to do when restore target already exists. The default is 'die', but can also be set to 'ignore' and return immediately.

  • mtime => INT

    Only recover file if file's mtime is the one specified. This can be useful to make sure that the file we recover is really the one that we trashed earlier, especially if we trash several files with the same path.

    (Ideally, instead of mtime we should use some unique ID that we write in the .trashinfo file, but I fear that an extra parameter in .trashinfo file might confuse other implementations.)

    See also suffix, which is the recommended way to identify and recover particular file.

  • suffix => STR

    Only recover file having the specified suffix, chosen previously during trash().

$trash->erase($file[, $trash_dir]) => LIST

Erase (unlink()) a file in trash.

Unless $trash_dir is specified, will empty all existing user's trash dirs. Will ignore if file does not exist in trash. Will die on errors.

Return list of files erased.

$trash->empty([$trash_dir]) => LIST

Empty trash.

Unless $trash_dir is specified, will empty all existing user's trash dirs. Will die on errors.

Return list of files erased.

NOTES

Weird scenario: /PATH/.Trash-UID is mounted on its own scenario? How about /PATH/.Trash-UID/{files,info}.

Related modules on CPAN:

  • Trash::Park

    Different trash structure (a single CSV file per trash to hold a list of deleted files, files stored using original path structure, e.g. home/dir/file). Does not create per-filesystem trash.

  • File::Trash

    Different trash structure (does not keep info file, files stored using original path structure, e.g. home/dir/file). Does not create per-filesystem trash.

  • File::Remove

    File::Remove includes the trash() function which supports Win32, but no undeletion function is provided at the time of this writing.
