Chown multiple dot files

Coolmar — Tue, 18 Oct 2005 12:34:37 GMT

Hi,

Is there a way to chown multiple dot files in a directory? Obviously, chown .* is not the way to go, but I am tired of chowing each and every dot file in a directory.

Thanks,
S

Hi Sally,

can we have

# chown -R owner:group

find . -type f -name '.*' -prune -exec owner:group {} \;

That does all the regular files but not the dot files (ie: .profile, .dt, .abc, etc)

chown XXX .[a-z,A-Z,0-9]*

this will change the ownership of most every dot file in a given directory.

oops

find . -type f -name '.*' -prune -exec chown owner:group {} \;

They're usually the first files in a long listing ("ll"). If you know how many there are, try this:

ll | grep -v total | head -7 | awk '{print $9}'

The 7 would be the number of files in the directory that you want.

You can put that into a for-do loop or a maybe an xargs pipe.

Not so elegant, but I hope that helps.

NOTE:
It will also chown the . files in subdirectories downstream from the current directiory.

one caveat for Alan's command:

as .. (i.e. the upper directory) is found as a result of the find command, it may try to change the ownership of the files in the directory above which may wreak havoc in certain cases.

My tests of the included find command show that it does not go to the parent directory, but it does travel down the subdirectories below.

Let regexp do the work for you (find is not necessary). You already know that .* will match . and .. (not good!) so just tell regexp to not include a match if the second character is a dot:

chown user1:group2 .[!.]*

As with any sweeping command using filename matching, always verify the results with a preview:

echo chown user1:group2 .[!.]*

Oops. This will not match . or .. but it does match directories and that might not be desired. In that case, use find to locate only files.
