У попередній відповіді згадується команда gio trash, що добре, наскільки це йде. Однак на серверних машинах немає еквівалента каталогу сміття. Я написав сценарій Баша, який виконує цю роботу; на (Ubuntu) настільних машинах, які він використовує gio trash. (Я додав alias tt='move-to-trash'у свій файл визначення псевдонімів; ttце мнемонічне значення для "сміття".)
#!/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.)
