=head1 NAME

trash-u - Trash files, with undo/redo capability

=head1 VERSION

This document describes version 0.14 of trash-u (from Perl distribution File-Trash-Undoable), released on 2014-12-05.

=head1 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

 # redo; now the *.bak files are trashed again
 % trash-u --redo

 # show history
 % trash-u --history

 # forget history; past actions can no longer be undone/redone
 % trash-u --clear-history

 # empty trash; this action is not undoable (the point is to reclaim space)
 % trash-u --empty

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

=head1 COMPLETION

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

=head2 bash

To activate bash completion for this script, put:

 complete -C trash-u trash-u

in your bash startup (e.g. C<~/.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.

You can also install L<App::BashCompletionProg> which makes it easy to add completion for Perinci::CmdLine-based scripts. After you install the module and put C<. ~/.bash-complete-prog> (or C<. /etc/bash-complete-prog>), you can just run C<bash-completion-prog> and the C<complete> command will be added to your C<~/.bash-completion-prog>. Your next shell session will then recognize tab completion for the command.

=head2 fish

To activate fish completion for this script, execute:

 begin; set -lx COMP_SHELL fish; set -lx COMP_MODE gen_command; trash-u; end > $HOME/.config/fish/completions/trash-u.fish

Or if you want to install globally, you can instead write the generated script to C</etc/fish/completions/trash-u.fish> or C</usr/share/fish/completions/trash-u.fish>. The exact path might be different on your system. Please check your C<fish_complete_path> variable.

=head2 tcsh

To activate tcsh completion for this script, put:

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

in your tcsh startup (e.g. C<~/.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.

=head2 zsh

To activate zsh completion for this script, put:

 _trash_u() { read -l; local cl="$REPLY"; read -ln; local cp="$REPLY"; reply=(`COMP_SHELL=zsh COMP_LINE="$cl" COMP_POINT="$cp" trash-u`) }

 compctl -K _trash_u trash-u

in your zsh startup (e.g. C<~/.zshrc>). 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.
