chmod directorys and files in subfolders

[SarahS93]

How can i search for all subfolders in a folder an change all folders to 775, and how can i search for all files in the subfolders for files and chmod them to 664 ?

You could modify the find expression so that it does not print objects for which the mode is already as desired. Other than that, how would you reduce writes without skipping some necessary changes?

find has the -exec argument, so you don't need those pipes.

find . -type d -exec chmod 775 {} \; && find . -type f -exec chmod 664 {} \;

Using -exec is much worse than using xargs. The form of -exec you suggest will run one chmod per entry found. Using xargs will batch up the calls to chmod.

find . -type d -exec chmod 775 {} \; && find . -type f -exec chmod 664 {} \;

works too but

chown -cR <user>.<group> * && find . -type d -print0 | xargs -0 chmod 775 && find . -type f -print0 | xargs -0 chmod 664

is 10 times faster and do not make so many writes on the disk.

No find needed...
