find . -name '*.mp3' -exec cp –parents \{\} ~/ostechnix \;

- find – command to find files and folders in Unix-like systems. - The dot (.) - represents we copy the contents from current directory. - -iname ‘*.mp3’ – search for files matching with extension .mp3. - -exec cp – execute the ‘cp’ command to copy files from source to destination directory. - –parents - create the intermediate parent directories if needed to preserve the parent directory structure. - \{\} – is automatically replaced with the file name of the files found by ‘find’ command. And the braces are escaped to protect them from expansion by the shell in some “find” command versions. You can also use {} without escape characters. - ~/ostechnix – target directory to save the matching files. - \; – indicates it that the commands to be executed are now complete, and to carry out the command again on the next match.

find . -name '*.PNG' -exec cp \{\} allpics/ \;

Ici nous sommes à la racine de l'arborescence à explorer et le dossier de destination est allpics.

compter les différences diff -y <(cd /chemin/du/dossier/1/ && ls -R) <(cd /chemin/du/dossier/2/ && ls -R) | wc -l

lister les différences dans diff.log diff -y <(cd /chemin/du/dossier/1/ && ls -R) <(cd /chemin/du/dossier/2/ && ls -R) > diff.log

ajouter grep -E \/ ou -d sur le ls permet de lister les répertoires
