Shell Script
 
Hey Everyone.

Im new to Linux and i have been asked at work to write a script. Im sort of struggling with it. anyway what i need it to do is:

Have a file called "userlist" and a script called "addusers". the userlist file has the fields "username, password, group, fullname". ok i need this script to read the userlist file (i got that working)

Ive also been trying the grep command to search for certian words etc.

But now i need to be able to capture those words that grep finds and make them global varibles or something so i can then create a user account from the data grep found.

Can anyone steer me in the right direction, any help is very much appreciated.

Thank you so much

Stinger,

If you post your script, you should get the comments you are looking for.

Not complete, but something to start with:
Code:
#!/bin/bash

cat userlist | while read LINE ; do
        test "${#LINE}" = "0" && break
        set $LINE
        # now fields are available as $1, $2, ...

        echo "User = $1 :"
        echo "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~"
        echo "    Password:  $2"
        echo "    Group:    $3"
        echo "    Full name: $4"
        echo
        echo
done

I suppose this would do the job for you
Code:
#!/bin/sh
num=`wc -l userlist |awk '{print $1}'`
for (( i=1 ; i <= $num ; i++ ))
do
useradd `cat userlist| head -n $i | tail -n 1 | awk '{print $1}'` ;
cat userlist | awk '{print $2}' | passwd --stdin `cat userlist | head -n $i |tail -n 1 | awk '{print $1}'`;
usermod -g `cat userlist | head -n $i | tail -n 1 | awk '{print $3}'` `cat userlist |head -n $i |tail -n 1  | awk '{print $1}'`;
chfn -f `cat userlist | head -n $i | tail -n 1 | awk '{print $4}'` `cat userlist |head -n $i |tail -n 1  | awk '{print $1}'`;
done
