Change Permissions in dir/sub-dirs

[panchpan]

Hello.
I have one main dir , which might have 100s of sub-dirs and files in it. Is there any command to be used for changing permissions to 755 of each components under main dir?

Thank you!

Hi,
chmod -R

see "man chmod"

The "-R" option of chmod is the obvious solution. If you want or need more flexibility, perhaps to apply different permissions to subdirectories than to the files within, you could use the find command:

find /start_dir -type d |xargs chmod NNN

-and-

find /start_dir -type f |xargs chmod NNN
