How To

using grep

grep -rwl '/path/' -e "string"
grep -rwl '/path/' -e "string" | grep 'path_string'

combining find and command using exec

• tous les dossiers appelés target

find -name target -type d

• effacer tous les dossier nommé "target" executer un rm recursif, le dossier target est utilisé part maven entres autres

find -name target -type d -exec rm -r {} \;

• chercher une chaine searched_string_in_file dans les fichers *.cxx

find . -type f -name "*.cxx" -exec grep "searched_string_in_file" {} \;

• ajouter -print pour afficher le fichier conteneur

find . -type f -name "*.cxx" -exec grep "searched_string_in_file" {} \; -print 

• filtrer le chemin d'access et afficher le fichier

find /path -path '*path_string*' -type f -exec grep -qw 'string' {} \; -print

• update all git subdirectories

find . -name .git -type d -exec git --git-dir '{}' fetch --all ';'
find . -type d -name .git -d 2 -exec git --git-dir '{}' fetch \; -print
find . -type d -name ".git" -exec git --git-dir '{}' pull \; -print
