ZoneO-tips for Mandriva Linux

How do I change permissions recursively?

 
 

There is a problem that happens frequently when

• Moving folders from a windows partition,
• Restoring folders from a CD or DVD.

All your permissions are lost. In other words, all files and documents are readable, executable, and writable by everyone... This can be a problem, for security reasons, but also for color-coding files in an xterm for instance.

What I usually want personnaly is to restore things so

• directory are readable, writable, and executable for the owner (and the owner only)
• files are readable and writable by the owner only, and not executable by anyone.

Well, it just takes a few commands:

# find all directories (recursively), and give the owner the permission
# to read, write and execute
find ./ -type d -exec chmod u+rwx {} ;
# find all directories (recursively), and remove all right to
# group members and the rest of the world
find ./ -type d -exec chmod og-rwx {} ;
# find all files (recursively), and give the owner the permission
# to read, write but not execute
find ./ -type f -exec chmod u+wr-x {} ;
# find all files (recursively), and remove all right to
# group members and the rest of the world
find ./ -type f -exec chmod og-rwx {} ;


That's all.
