here i check the lenght of the shell field which is the last field in /etc/passwd file. you may do some other check if you want to.

awk -F":" ' {
if ( length($NF) > 0 )
printf("%s %s SHELL\n", $1, $5)
else
printf("%s %s notshell\n", $1, $5)
}' /etc/passwd;

NAME
rpc.yppasswdd -- NIS update password file daemon SYNOPSIS
rpc.yppasswdd [-d directory] [-noshell] [-nogecos] [-nopw] [-m arg1 [arg2 ...]] DESCRIPTION
rpc.yppasswdd must be running on the NIS master server to allow users to change information in the password file. The options are as follows: -d directory Change the root directory of the password file from ``/'' to directory.

The databases need to be created only once with the following command: pwd_mkdb -d directory directory/etc/master.passwd -noshell Don't allow changes of the shell field in the passwd file. -nogecos Don't allow changes of the gecos field in the passwd file. -nopw Don't allow changes of the password in the passwd file. -m arg1 [arg2 ...] Additional arguments to pass to make in /var/yp.
