Need help with a find command

wvsa — Thu, 20 Jan 2011 06:08:27 GMT

Good evening all;

Looking for some help regarding a find command. I need to go through all the /home directoris and change all files used during the user login process, eg. .profile, .sh_history, etc that have permissions of 644 and change them to 600. Need the find command to skip directories, don't want to change the permissions on the .ssh directory for example.

Thank you in advance for your input

Norm

find /home -type f -name ".*" -perm 644 -exec chmod 600 {} +

I think , it must be;

find /home -type f -name ".*" -perm 644 -exec chmod 600 {} \;

Nothing wrong with the Posix standard: -exec ... {} +
Especially if you want performance.

Note: -name ".*" changes all dot files, not just "files used during the user login process". Even in subdirectories.

Hi:

To add to Dennis's comments, have a look at the 'find(1)' manpages under the '-exec' option. The differences between the ';' and the '+' terminator (including performance) are nicely discussed with examples there:

As usual, the manpages are your friend :-)

Dennis;

You have identified the source of my problem, you can't use ".*" as this will indeed change the .. perms, not good.

So how can I get around this, is it possible with the find command?

Thank you for your input.

This should only happen if you do NOT specify the item type you are looking for.

If you use the example above where '-type f' is specified then you should only get regular files and not directories.

Really? Did you try it? And "-type f"
didn't help?

As usual, showing actual commands with their
actual output can be more helpful than vague
descriptions or interpretations (or
speculations).

man find

Look for "!". It should work with something
like
-name ..
too. If you really needed to do that.

All;

Thank you for all your responses, as it turns out I was making it more difficult than it should be.

Thread closed.

Right. You don't need -type f because find(1) automatically skips . and .. because it wouldn't make progress if it looked at them.
You do have to worry when using ls(1) though.
