Thank you. This works in the terminal perfectly. However, it doesn't seem to work in a bash script. Been messing around with all sorts of way for hours now.

An example :

Code:
#!/bin/bash
# Script to add a startup item

username=somethingrandom

cp /etc/init.d/originalfile /etc/init.d/$username
sed 's!changeusername!$username!' /etc/init.d/$username > tempfile
mv tempfile /etc/init.d/$username
chown root:root /etc/init.d/$username
chmod 777 /etc/init.d/$username

I've renamed the file in the script to changeusername so its easier. However it doesn't work with the string $username present. If i were to replace $username with "somethingrandomhere" then it would work. However, i want it to change according to the username that i've given in the script.

(Script has been modified for the thread so it would be less complicated. In the real script, I would be asked to input the username)

lppasswd

lppasswd(1)							    Apple Inc.							       lppasswd(1)

NAME

       lppasswd - add, change, or delete digest passwords.

SYNOPSIS

       lppasswd [ username ]
       lppasswd -a [ -g groupname ] username
       lppasswd -x username

DESCRIPTION

       lppasswd  adds, changes, or deletes passwords in the CUPS digest password file, passwd.md5. When run by a normal user, lppasswd will prompt
       for the old and new passwords.  When run by the super-user, lppasswd can add new accounts (-a username), change	existing  accounts  (user-
       name), or delete accounts (-x username) in the digest password file. Digest usernames do not have to match local UNIX usernames.

OPTIONS

       lppasswd supports the following options:

       -g groupname
	    Specifies a group other than the default system group.

SECURITY ISSUES

       By  default,  the lppasswd program is not installed to allow ordinary users to change their passwords. To enable this, the lppasswd command
       must be made setuid to root with the command:
       chmod u+s lppasswd

       While every attempt has been made to make lppasswd secure against exploits that could grant super-user privileges  to  unprivileged  users,
       paranoid system administrators may wish to use Basic authentication with accounts managed by PAM instead.
