Svuotare Automaticamente I Cestini Di Tutti Gli Utenti
Autotrash
Autotrash e' uno script che vi permette di tenere sotto controllo i cestini di tutti gli utenti o solo il vostro. Autotrash รจ su github qui: https://github.com/bneijt/autotrash
Per installarlo in tutto il sistema vi basta mandare in esecuzione i seguenti comandi:
$ sudo apt-get install pipx $ pipx install autotrash $ sudo ln -s ~/.local/pipx/venvs/autotrash/bin/autotrash /bin/autotrash
Ci sono tante altre opzioni disponibili che sono spiegate nel manuale qui: https://github.com/bneijt/autotrash/blob/main/doc/autotrash.md
Per controllare solo il vostro cestino vi basta il comando
$ autotrash -d 30 --trash_limit 1000
Per fare in modo che il controllo avvenga in automatico per tutti gli utenti, bisogna mettere il comando nella cartella /etc/profile.d/, questo file deve essere un normale file di testo, ad esempio autotrashpertutti.sh e deve avere solo il comando. Ad esempio, in modo che il cestino di ogni utente non sia maggiore di 1Gb:
/usr/bin/autotrash -td 30 --trash_limit 10000
Vecchia soluzione
Prima di autotrash avevo scritto il seguente script che permette di impostare quanto spazio concedere al cestino di ogni utente, e ripulirlo quando supera una certa dimensione. Magari vi puo' essere utile per altre necessita'.
Prima di tutto bisogna mettere questo script e chiamarlo delete_spaces.pl, metterlo in /usr/bin/:
#! /usr/bin/perl
use File::Find;
finddepth sub { # finddepth so directories are done AFTER their contents
my $old = $_;
tr/ /_/ or return; # don't do anything if you don't have spaces
-e and return; # don't rename over an existing file!
rename $old, $_ or warn "cannot rename $old to $_: $!";
}, "."; # starting directory
Spero possa essere utile a qualcuno, consiglio di metterlo in "/etc/cron.daily/" e renderlo eseguibile:
#! /bin/bash
