You can do something like this:

for i in $(cat /etc/passwd | awk -F: '{print $1}'); do chown $i.GROUPNAME; done

Actually, you don't do that! It won't work....

for i in $(cat /etc/passwd | awk -F: '{print $1}'); do adduser $i GROUPNAME; done

Will that add everyone in /etc/passwd? If so there are profiles in

I believe you can just modify the spreadsheet and use the newusers command again - it can update bulk users as well as create them. Have a look at "man newusers" and "man 5 passwd" for details. -----Original Message----- From: Thomas Adam To: Andrew Nix; suse-linux-uk-schools@suse.com Sent: 8/1/03 12:00 PM Subject: Re: [suse-linux-uk-schools] addins users to groups....... 500+ --- Andrew Nix wrote: > > --- Thomas Adam wrote: > --- Andrew Nix there

I am fully aware of that, and it was a very quick hack.

I have a spreadsheet that was used to create all the profile and I want. I used a commmand something like:

addnewuser <filename of spreadsheet>

and it created them all for me! Can something similar be done with groups?

Assuming that you have the list of users, export it to a cvs (a comma separated file) and issue the command: for i in $(cat ./the_file | awk -F, '{print $NUM}'); do useradd $NUM -G groupname; done You'll have to change the above so that $NUM is the column number that the username appears in (i.e. $1, $2, etc) and change "groupname" as appropriate.

I wasn't aware of that :) Mind you, I always like the generic approach, Chris, and it should work.... -- Thomas Adam

Well, assuming it is Office2000, etc, just click "save as" then select the filetype as cvs.... Alternativelty, you dont need to export it if you can manually extract all the usernames and save them to a separate plain text file.

Sorru, I thought I had explained :( a cvs file is a comma separated list of all your columns in your spreadsheet, i.e. say you had a spreadsheet like this: 1 2 3 a zz zz aa b qw gh xz c vf tg jk then your cvs file would look like: zz,zz,aa qw,gh,xz vf,tg,jk

yes, as long as the usernames are listed one after the other in the file like this: user1 user2 user3 etc... -- Thomas Adam

Hi I think you mean csv as in comma separated values and not cvs. Incidentally I am in my annual 'update the server' routine and I use speadsheets to generate multiple bash commands to add my 1500 users, set quotas etc along with expect to automatically add passwords. This is not as elegant as Thomas's routines but it has worked for the last 4 years. Dave

Yes, you're quite right. That's one of my more classic freudian slips :)

...

Yes, not a bad idea there, but you have to be careful about security, especially if you leave the spreadsheet non-encryped. I use expect all the time too, for automated tasks that require user interaction of some kind.

Granted my routine was off the top of my head, but I am sure that it will work, nevertheless. -- Thomas Adam ===== Thomas Adam "The Linux Weekend Mechanic" -- www.linuxgazette.com ________________________________________________________________________ Want to chat instantly with your online friends?
