How can we remove Email Forwarding from 3000 users

Hello,

My question is for send mail server 12.5
we enabled forwarding on all users now How can I remove the forwarding on 3000 users at once.
Below is the method which I have adopted right now to remove the forwarding from all users…
sudo /bin/rm /home/username/.forward
this is very hectic for me to delete one by one. Is there any script which we have to use so that my activity become more easier..?

looking forward for your response and kind assistance

sudo /bin/rm /home/*/.forward

I would STRONGLY recommend to do a full backup before doing this. :-P

Hmm, he said 3000 users, not all users.
If there are more, then the backup is needed indeed :P

Is there a list of these 3000 users?

yes indeed!

you are right we do have more than 3000 users.
Look the scenerio is like we have a list of users in notepad or excel file now i have to delete these specific users which are only in that file...
rst of them should not be deleted in any case.
thanks

oki,
assuming
- you have a list of usernames
- the list is one name per line, ideally ending in unix linefeed convention. aka no windows style CR/LF
- the username are sane (no special chars, spaces, etc)
- the usernames are equal to the homedirectory names
- the homedirectories are under /home
- you are root

then something like this comes to mind:

Code:

---

for USERNAME in `cat userlist`; do ls -la /home/$USERNAME/.forward ; done

---

Look for erros, look for consistency, look for correct number ( | wc -l).
If you are happy with what you see, replace the ls -la with a rm -f.

You can simply use find command

to find

Code:

---

find /home/ -name '.forward' -print

---

and

Code:

---

find /home/ -name '.forward' -delete

---

to delete them.

And yes, it would be better to perform backup before doing this.

The find will delete all.
Jamikhan needs to delete only 3000

Ohh, yes, thank you.
I just missed that message.

As irithori said, this will NOT work with usernames like "John Smith" as that will try to remove a user "John" and a user "Smith". Just wanted to point that out.

You could do also the inverse:

Code:

---

for user in /home/*; do
# check if $user should be deleted in some or the other way
if [ fgrep SOME_ARGS ]; then
  rm -rf $user;
fi
done

---

i will check all these options
thanks in advance..
but i need to be sure that it will not harm my user IDs..it will just remove email forwarding from them....?
