My dear friends,
you have used 'useradd' command in the script through which we can only add the user name. But for adding password you should use 'passwd' command because password is also mandatory.

#variable
i=1
while [ i let 10 ]
do
/usr/sbin/useradd user$i -d /home/user$i -s /bin/ksh -m
user$i
i=$(expr $i + 1)
done

A file has multiple records each having three 30-bit long fields(field1,field2,field3).There is also a lookup file,LOOK_UP.dat.Now, we need to consider only the last ten digits of field1 and lookup the file LOOK_UP.dat. If there a match then field2 and field3 should replaced with corresponding data from the lookup file. otherwise that particular record,for which there is no match, should be stored in a seperate file.
