BASH Comment supprimer des repertoires vide

Posted on by

Une question simple avec une réponse tout aussi simple, comment qu’on fais pour virer un nombre N de répertoire vide sans devoir faire un ‘rm -rf’ a la main pour chaque répertoire.

Le find qui sert a supprimer tous les rpertoires vide d’un repertoire

find . -maxdepth 1 -type d -empty -exec sh -c 'rm -rf "{}" && echo "{}" deleted' \;

Je crée des répertoires bidon pour les tests :p

hio@fantasy:~/test$ mkdir {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,notemptydir} 
hio@fantasy:~/test$ echo maisblu > notemptydir/testfile

BASH Comment supprimer les fichiers de backup d’emacs

Posted on by

Voila un script qui sert a supprimer tous les vilains fichiers de backup d’emacs.

eclean.sh

#!/bin/bash
find . -name '#*#' -exec rm -f {} \; -or -name '*~' -exec rm -f {} \;

et une version un poil plus évoluer, ça peu qd même être bien de voir ce qu’on supprime :p

eclean.sh

#!/bin/bash
echo 'Cleaning emacs backups files ...'
find . -type f -name '#*#' -exec sh -c 'rm -f {} && echo {} deleted' \; -or -name '*~' -exec sh -c 'rm -f {} && echo {} deleted' \;

ce qui donne au final

hio@fantasy:~$ eclean
