Mass change ownership

tbeehler · 05-22-2009, 01:32 PM

Hello all,

I used a script to mass create some folders

/mnt/windows/foo
/mnt/windows/bar
etc x 100

on the folders, the folder ownership looks like

root.group
root.group
etc x 100

So, my question is, is there a way to say "whatever the folder name is, use that as the user name in chown"?

so it would grab the folder name "foo" and go:

chown foo.group foo/

and go on to the next folder name?

like find . -type d -exec chmod 755 {} \; only with chown?

It seems like it would be easy, but I'm having a tough time finding the syntax. Does anyone else know of a way to do this? Thanks in advance!

My bad. I thought I knew what I was talking about. On review, it seems I'm badly mistaken, so I've deleted my remarks.

For anyone interested, I'd written:

for file in [/mnt/windows/foo,/mnt/windows/bar/ext\ x\ 100]
do
chown $basename $file
done

Note the excaped spaces in ext\ x\ 100 to prevent bash from parsing the path/filename as three seperate inputs to the for loop, withou comma delimiter.

The loop says basically to take the basename of the path and use that as the owner name input to the chown command.

Code:

for dir in $(find . -type d)
do
  owner=${dir##*/}
  chown ${owner}:group $dir
done

Anyway, I guess that in your script at some point you already have the path and the name of the directory you're going to create, so that you can just add the chown statement immediately after mkdir.

I forgot to reply to you, so I apologize for that, but your code worked perfectly! Thanks!
