The simplest script in unix would be
------------------------------------------------------------------------
#! /bin/sh
adduser --conf /etc/mailuser.conf $1
------------------------------------------------------------------------
The first line indicates you are running a bourne shell script, which is
the most portable type of script. The $1 is the first argument. After
you save the script, you should make it executable:
chmod +x addmailuser
Then as root, you would run it like
./addmailuser joe
to add user joe (root does not have the current directory in its path).
Traditionally, most unix commands can take any number of arguments to do
the same thing with. A script that could add more than one user in one
run would look like:
------------------------------------------------------------------------
#! /bin/sh
for u in $*; do
adduser --conf /etc/mailuser.conf $u
done
------------------------------------------------------------------------
Now you can type
./addmailuser bill hilary chelsea
