SYNOPSIS

 # trash some files, but in simulation mode, not really trashing the files
 % VERBOSE=1 trash-u --dry-run *.bak

 # trash some files, for real
 % trash-u *.bak

 # list trash contents
 % trash-u --list-contents

 # trash some more files
 % trash-u * .tmp

 # oops, made a mistake; no worry, let's undo; now previous trashing is reversed
 % trash-u --undo

 # undo again; now the *.bak files are also restored
 % trash-u --undo

 % trash-u --empty

 # display help for more options
 % trash-u --help

USING AS rm REPLACEMENT

trash-u can be used as rm replacement (a.k.a. alias) with some caveats:

  • trash-u deletes directories by default

    That is, it behaves as if -R rm option is in effect.

  • Some rm options exist but do not have any effect (noop)

  • Some rm options are still missing/unknown

    This include: -i/-I/--interactive, --one-file-system, --no-preserve-root.

COMPLETION

This script has shell tab completion capability with support for several shells.

bash

To activate bash completion for this script, put:

 complete -C trash-u trash-u

in your bash startup (e.g. ~/.bashrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.

It is recommended, however, that you install shcompgen which allows you to activate completion scripts for several kinds of scripts on multiple shells. Some CPAN distributions (those that are built with Dist::Zilla::Plugin::GenShellCompletion) will even automatically enable shell completion for their included scripts (using shcompgen) at installation time, so you can immadiately have tab completion.

tcsh

To activate tcsh completion for this script, put:

 complete trash-u 'p/*/`trash-u`/'

in your tcsh startup (e.g. ~/.tcshrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.

It is also recommended to install shcompgen (see above).

other shells

For fish and zsh, install shcompgen as described above.

ENVIRONMENT

=> str

Specify additional command-line options

CONFIGURATION FILE

This script can read configuration file, which by default is searched at ~/.config/.conf, ~/.conf or /etc/.conf (can be changed by specifying --config-path). All found files will be read and merged.

To disable searching for configuration files, pass --no-config.

Configuration file is in the format of IOD, which is basically INI with some extra features. Section names map to subcommand names.

You can put multiple profiles in a single file by using section names like [profile=SOMENAME] or [SUBCOMMAND_NAME profile=SOMENAME]. Those sections will only be read if you specify the matching --config-profile SOMENAME.

List of available configuration parameters:

Common for all subcommands

 format (see --format)
 format_options (see --format-options)

For subcommand 'empty'

For subcommand 'list_contents'

For subcommand 'trash'

 files (see --files)
