Le risposte precedenti menzionano comandi trash-clie rmtrash. Nessuno di questi si trova di default su Ubuntu 18.04, ma il comando gioè. gio help trashUscite comandanti :
Usage:
gio trash [OPTION…] [LOCATION...]
Move files or directories to the trash.
Options:
-f, --force Ignore nonexistent files, never prompt
--empty Empty the trash
Ho provato usando gio trash FILENAMEdalla riga di comando e funziona proprio come se avessi selezionato il file nel browser dei file e fatto clic sul pulsante DEL: il file viene spostato nella cartella Cestino del desktop. (Il comando non richiede la conferma anche se non ho usato l' -fopzione.)
L'eliminazione di file in questo modo è reversibile, pur essendo più conveniente di ridefinire rmdi essere rm -iper la sicurezza e di dover confermare ogni eliminazione, che si lascia ancora fuori di fortuna se si conferma accidentalmente una cancellazione non si dovrebbe avere.
Ho aggiunto alias tt='gio trash'al mio file delle definizioni alias; ttè un mnemonico per To Trash.
Aggiunto alla modifica il 27/06/2018: sui computer server non esiste un equivalente di una directory cestino. Ho scritto il seguente script Bash che fa il lavoro; su macchine desktop, utilizza gio trashe su altre macchine, sposta i file dati come parametri in una directory cestino che crea. Script aggiornato il 05-09-2019.
#!/bin/bash
#
# move-to-trash
#
# Teemu Leisti 2019-09-05
#
# This script moves the files given as arguments to the trash directory, if they
# are not already there. It works both on (Gnome) 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 functionality of restoring a trashed file to its
# original location, nor that of emptying the trash directory; rather, it offers
# an alternative to the 'rm' command, giving the user the peace of mind that
# they can still undo an unintended deletion before emptying the trash
# directory.
#
# To determine whether it's running on a desktop host, the script tests for the
# existence of the gio utility and of directory ~/.local/share/Trash. In case
# both exist, the script relies on the 'gio trash' command. Otherwise, it treats
# the host as a server.
#
# There is no built-in trash directory on server hosts, so the first invocation
# of the script creates directory ~/.Trash/, unless it already exists.
#
# The script appends a millisecond-resolution time stamp to all the files it
# moves to the trash directory, both to inform the user of the time of the
# deletion, and to avoid overwrites when moving a file to trash.
#
# 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 trash.

gvfs-trashin passato, ma non ho mai avuto bisogno di ripristinare dalla riga di comando fino a quando non hai suscitato la mia curiosità. La risposta alla domanda collegata può essere di aiuto.
