bash trouver le toucher
find . -type f -exec touch {} +
steamboatid
find . -type f -exec touch {} +
-exec ... \; will run one item after another.
So if you have three files, the exec line will run three times.
-exec ... {} + is for commands that can take more than one file at a time
(eg cat, stat, ls).
The files found by find are chained together like an xargs command.
This means less forking out and for small operations, can mean a substantial speedup.
