i want to write a little shell script called "addmailuser" w/c executes "adduser --conf /etc/mailuser.conf" where mailuser.conf contains info like making their default shell /bin/false. in dos, that "addmailuser" file will simply contain "adduser --conf /etc/mailuser.conf %1" where %1 is the first parameter that it sees, that is, the name of the user i want to add ... but how do u do this in linux ??? hope someone can guide me on this, TIA caa
