I want to change every file and dir to chmod xx0

jasong · 2007-09-04, 15:17

At first the title was 'I want to change every file and dir to chmod 770.' Then, I realized that might not be such a good idea.

So, assuming x means that number stays what it is, is there an easy way to change everything on my Linux box to 'chmod xx0'?

Hi Jasong,

The option you are looking for is -R.

chmod -R xx0 *

x is as you defined it.

This would change all files, sub-directories & files within the current sub-directory.

Use with caution!

You might also want to do a chmod -R +X directory if you want your directories to have execute permission, so you can chdir() into them.

I think you want

chmod -R o= .

(or chmod -R o-rwx . if the chmod doesn't support = ; SunOS doesn't IIRC)
This changes the current dir and its sub-dirs. Using * will miss files starting with a dot and the current directory.

SCO Unix, has the fixmog and integrity commands to ensure correct & safe permissions. Is there anything similar in Linux?

Code:

chmod -R o=-r-w-x *

No idea what the star does, for a moment I thought it meant look at the end of the post for a clarification.

It is a wildcard.

Probably, although we are not aware of it.

We just use common sense and experience to guide us.

Understanding file permissions helps, too.

tripwire? I guess it's similar

You'd need to run tripwire on the virgin system first.

The other option is to use the rpm command with the with the setperms option for each package installed.
