help with script

[pacho baratta]

i have a txt file with a list of username one by line, say:
user1
user2
user3
.....


i'd like to avoid to insert all these users by hand (about 1000 users)
so i build a script to add users, make dirs and something useful to me

my goal is to get a way to process txt file and send all users, one by
one, to my script.

cat txtfile | ./script

is processing only the 1st user, not the others.

any idea to automatize this process?
tnx, pacho

while loop, $1 and shift can also do it. 
here is a sample scripts 

let us say u user list are in a file called, users. The following will be
mail to all users in the list. Save this script, let us says, myscript. 

while [ $1 ] 
do
	mail `cat users`
	shift
done 


If I want to use the above scripts to send mail to all users in the file, 

./myscripts `cat users`


pls replace the mail command name with your own scripts name 
Note:- You must use `cat users` with backquote ( not single quote )

while read user ; do
	useradd -m $user
	do_whatever_else $user
done

This presumes that this is a script you execute as `script < txtfile`
If you were doing it as a one-liner, then the last line would be
`done < txtfile`

Note that the < textfile would have to be after the done construct on
the while loop.  if you did:  `while read user < txtfile`, the read
command would open txtfile, and read the first line .... over and over
and over again  (is this what you're seeing?)


`useradd -m $user` should create the user and their home directory --
normally, in /home/$user , but you can change that with
`useradd -m  -d /some/path/$user $user `
