[olug] Chgrp / chown question

[Tim - DZ]

N/M replied too quickly, thanks Kenton.

I didn't realize you could chmod groups without specifying the owner.
So the answer to my own question is:

chmod -R --from=:grpB :grpQ ./

I didn't read the man page close enough to see that a leading : could be
used.

I knew I wasn't stating my question quite clearly...

I don't want to do all the files, just the specific ones...
So:

[root at server]# ls -al 
total 32
drwxr-x--x    6 root     grpA         4096 Aug  8 08:50 .
drwxr-xr-x    8 owner1   grpA         4096 Sep 11 14:05 ..
drwxr-xr-x    9 owner1   grpB         4096 Feb 17  2003 These
-rwxrwxr-x    1 root     grpC         2886 Feb 17  2003 DirNFile
-rwxrwxr-x    1 owner2   grpA         3126 Feb 17  2003 Names
drwxr-xr-x    3 owner1   grpC         4096 Feb 17  2003 Dont
drwxrwx--x    6 owner2   grpB         4096 Feb 17  2003 really
drwxr-xr-x    7 owner3   grpA         4096 Aug  8 09:14 matter

I want all the files/dirs owned by owner1 to now be owned by a user
called "joe" (even on files/dirs lower that current) and leave
files/dirs owned by owners2,3 and root alone.

chmod -R -from=owner1 joe

Ok, so that's good to go

Now I want all files/dirs in the grpB to now be in grpQ (even on
files/dirs lower than current) And leave files/dirs owned by groups A
and C alone.

????

You can use "chgrp -R"  Or do them both at once with chown -
$ chown -R user.group *
               ^
Some variants of chown use ":" as a delimiter and not "." as I used
above. Kent
