change ownership script

hi there,

i'm trying to write a script that changes the ownership of the file .procmailrc in all the users home directories as their's

for instance at the moment it's like this

[root@mail pma]# ls -lsa
total 28
4 drwx------ 3 pma 10000 4096 Apr 7 09:27 .
12 drwxrwxrwx 490 root root 12288 Apr 7 08:10 ..
4 drwx------ 3 pma 10000 4096 Apr 7 09:20 mail
8 -rwx------ 1 root root 4441 Apr 7 09:27 .procmailrc

i want it to look like this for everyone

[root@mail pma]# ls -lsa
total 28
4 drwx------ 3 pma 10000 4096 Apr 7 09:27 .
12 drwxrwxrwx 490 root root 12288 Apr 7 08:10 ..
4 drwx------ 3 pma 10000 4096 Apr 7 09:20 mail
8 -rwx------ 1 pma 10000 4441 Apr 7 09:27 .procmailrc

Code:

$ su
# cut -f1,6 -d: /etc/passwd | sed -e's/:/ /' -e's/^/chown /' -e's/$/\/.procmailrc/' > /tmp/doit.sh
# vi /tmp/doit.sh   (verify that this looks like what you want to do, then...)
# sh -x /tmp/doit.sh
#

thats a great script! i'm impressed by it, but i'm using winbind with virtual users ... so there not listed in the /etc/passwd file ...

This one is not as smart as heartig's, but what about:

Code:

cd /home
for nfile in *
do
        if [ -d $nfile ] && [ -e /home/$nfile/.procmailrc ]
        then
           chown $nfile:10000 /home/$nfile/.procmailrc
        fi
done

Obviously you have to run it as root.

This changes the .procmail rc to the user as owner. If you want to change to owner 'pma' change the
chown $nfile ...
to
chown pma ...
This was not quite clear to me.
