Interrogate file owner

Monte Heeren — Mon, 20 Feb 2006 17:18:50 GMT

Trying to find a script to delete files that are older than AND that are not owned by a certain user.

Syntax used:
find . -depth -mtime +
-exec rm {} \;

This script works great to remove files that are certain days old, but I need to add to it to Not remove the file if it is owned by a paticular user. Any ideas on how to do this?

Add ! -user username

! negates whatever test you put it in front of.

find . -depth -mtime +30 ! -user mickey -exec rm {} \;

will delete all files that have not been modified in the last 30 days and not owned by user "mickey".

When developing any finds like this, it is always better to -exec a safe command like "ls -l" until you are certain that your filters are just right and then switch to the real "rm" command.

Can not get the ! operator to work.

If I enter:
find . -user mickey -exec ll {} \;
it will return with only files that are
owned by mickey. This works great.

But if I enter:
find . ! -user mickey -exec ll {} \;
it returns with all the files in the dir,
including the files owned by mickey.

Look like the ! operator is not working.
Is there another "NOT" character to use?

Are you using "csh"? If so, the ! character means something else. Try putting a backslash "\" in front of it.

I suspect that you are ll'ing directories. In that case, eventhough the directory is properly filtered all files under that directory are listed. What you should do is add a '-type f' filter so that only regular files are found.

You didn't bother to indicate your HP-UX version but I would also make sure that the latest find cumulative patch is installed. For 11.11, it's PHCO_30746.

Hi Monte,

You need to make it boolean.
Surround the two operators with ( ) - separate them with spaces from the operands AND use -a for the AND operator.

HTH,

oh, I see, it's returning "." in the set, and this will automatically list everything in any subdirectory which matches the return set. In other words, since "." is returned, everything under "." is listed also.

Try adding "-type f" to the command:

find . ! -user mickey -mtime +30 -type f

To make sure you don't list a directories contents you could also add a '-d' to your 'll':

# find . ! -user mickey -mtime +30 -type f -exec ll -d {} ;

Hi Monte,

Surround the two operators with ( ) - separate them with spaces from the operands AND use -a for the AND operator.
And they need to be escaped with leading \

Thank you all for your quick response.
This is the only place for Unix help!

I added the -type f to the end of the command and it works perfectly.
