पिछले उत्तर में कमांड का उल्लेख किया गया है gio trash, जो अभी तक ठीक है। हालांकि, सर्वर मशीनों पर, कचरा निर्देशिका के बराबर नहीं है। मैंने एक बैश स्क्रिप्ट लिखी है जो काम करती है; (Ubuntu) डेस्कटॉप मशीनों पर, यह उपयोग करता है gio trash। (मैंने alias tt='move-to-trash'अपनी अन्य परिभाषाओं की फ़ाइल में जोड़ा है; tt"टू ट्रैश" के लिए एक महामारी है।)
#!/bin/bash
# move-to-trash
# Teemu Leisti 2018-07-08
# This script moves the files given as arguments to the trash directory, if they
# are not already there. It works both on (Ubuntu) desktop and server hosts.
#
# The script is intended as a command-line equivalent of deleting a file from a
# graphical file manager, which, in the usual case, moves the deleted file(s) to
# a built-in trash directory. On server hosts, the analogy is not perfect, as
# the script does not offer the functionalities of restoring a trashed file to
# its original location nor of emptying the trash directory; rather, it is an
# alternative to the 'rm' command that offers the user the peace of mind that
# they can still undo an unintended deletion before they empty the trash
# directory.
#
# To determine whether it's running on a desktop host, the script tests for the
# existence of directory ~/.local/share/Trash. In case it is, the script relies
# on the 'gio trash' command.
#
# When not running on a desktop host, there is no built-in trash directory, so
# the first invocation of the script creates one: ~/.Trash/. It will not
# overwrite an existing file in that directory; instead, in case a file given as
# an argument already exists in the custom trash directory, the script first
# appends a timestamp to the filename, with millisecond resolution, such that no
# existing file will be overwritten.
#
# The script will not choke on a nonexistent file. It outputs the final
# disposition of each argument: does not exist, was already in trash, or was
# moved to the trash.
# Exit on using an uninitialized variable, and on a command returning an error.
# (The latter setting necessitates appending " || true" to those arithmetic
# calculations that can result in a value of 0, lest bash interpret the result
# as signalling an error.)
