without adding each person individually? As I think I might be sat in this seat for the next two weeks adding everyone and miss my holiday to Ibiza! Cheers

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 The above will work!!!

Will that add everyone in /etc/passwd? If so there are profiles in there that dont need to be added to the group. I should have said this earlier.

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.

The above will work!!!

Hmm, It seems I am having a lapse in my typing. Once and for all, the _correct_ way is to do: for i in $(cat ./the_file); do useradd $i -G <groupname>, ; done

As it was just easier to copy all the usernames into a text file will the this same command work? If so what do I write for $NUM, as there are no columns to be defined? Is there an addgroup cammand that could also do the same thing or am I barking up the wrong tree?

(see above). Since you only have one column, invoking awk in this case is superfluous and unnecessary. You might just was well cat the file. You'll also notice that I have got <groupname> followed by a comma, and then <moregroups>. This is so that you can specify more than one group to add if need be. There is no "addgroup" command, as it is all contained within useradd. In debian, one can do it more simpler, but this is SuSE, so.... HTH, -- Thomas Adam

I tried this command but i very time I run it, it just says group unknown. This is the exact command I issue:

for i in $(cat ./Group\ Adding); do useradd $i -G @Students; done

Im in the directory where the list of users is when the command is run. Can anyone see if Im doing something wrong?

I appologize for getting the command wrong. I removed the @ before Students. But It tells me the user already exsists and doesnt add them to the group. Does anyone have any idea what im doin wrong?

Yes, I think that I am confusing the issue by a factor of X^Y. Unlike Debian's 'useradd', SuSE doesn't offer the same functionality. Therefore, still using the same command as you have been using, change "useradd" for "usermod" and then try it. -- Thomas Adam

I changed the it to usermod. But I get the reply user Students doesnt exsist. Below is the exact command issued. Is there something wrong with it? Or is theresomething else i need to add to it?

for i in $(cat ./KS3_20023_PUPILS.csv | awk -F, '{print $1}'); do usermod $1 -G @Students; done

I also tried it with a text file and the command is this:

for i in $(cat ./Group\ Adding); do usermod $i -G Students; done

I get the same error message with the above code. However, it does work fine on SuSE8.2 if you use useradd instead of usermod :-) for i in $(cat ./newusers); do useradd $i -G students; done Alastair

But each time I get the same response. Any idea anyone? Cheers

Hi Andrew Its a syntax problem - usermod requires the login name after the group for i in $(cat ./newusers); do usermod -G students $i; done this works fine Alastair On Friday 08 August 2003 09:57, Andrew Nix wrote:

I use 8.2 and I agree it would work if the users werent already set up. But as they are it just tells me that they do exsist! Any other ideas?

Cheers Alastair. This command worked a treat. I apprcaite everyone help for this long and very dragged out problem. I feel so relived that something finally worked :-)

Hi Andrew
