Script to block userid creation more that 8 characters

peterdin · 10-17-2013, 04:12 AM

Hi Guys,

I have one script which is used to add new user in the system.

This is how we add new user in system:-

Code:

 sudo /opt/local/bin/new-user 114 ranivarm "Rani Varma(Libo Technical User)" INC00001111

Where
114:-is the site id
ranivarm:- is userid
"Rani Varma(Libo Technical User)" :- comment
INC00001111:- ticket number

The script is little big, so here is part of that script:-

Code:

case $steps2skip in
(help)  die "$advanced";;
(password)      steps2skip=124;;
(enable)        steps2skip=123;;
([1-4]*)        ;;
esac

username=${1:?username required: $usage} shift
ticket=$3
descr="$*"


#
# assertions
#

grep -c ${group}  /etc/group >/dev/null ||
        warn "Warning: group $group is not in /etc/group"

grep -c $shell /etc/shells >/dev/null ||
        warn "Warning: shell $shell is not in /etc/shells"



warn "Checking accountname ${username:?}"

if [[ $steps2skip = *1* ]]; then

        /bin/logins -xol $username ||
                die "account $username does not exist!"
        /bin/getent passwd ${username} ||
                die "account $username does not exist!"

        eval home=~${username}

else    : step 1: creating /etc/passwd entry

        /bin/getent passwd ${username} &&
                die "account $username already exists!"
        /bin/logins -xol $username

Could you please tell me what entry should I enter and where should I insert it?

Thanks
Peter

Code:

username=${1:?username required: $usage} shift
[ ${#username} -gt 8 ] && die "username length > 8."

Thanks a lot for this. But my main problem is where exactly to insert these lines as this script is way big created by someone in 2005.
Would you please guide me where exactly can I insert these lines? can I insert it anywhere in script/

Thanks a lot!

Look up the first line I posted in your script and post the second one beneath it.
