yeah, I figured out id was outputting the "no such user" to stderr just a moment ago.

Your suggestion worked brilliantly.

Thanks!

Incase anyone's interested, here's the "draft 1". It could be streamlined more, and I also plan to add the ability to delete members, and maybe compare the group against the input, and only add/remove those users that differ.

Feel free to use, though, I doubt it's worth much to people other than myself. =)

Code:

#!/bin/bash

#This script will take two arguments, the group name, and the user list. 
#It is recommended that the group be cleared before running this script since
#it will not remove people from the group.

dirnode="/LDAPv3/ldap.example.com"

if [ "$#" != "2" ]; then
echo -e "Usage of the groupadd script: $0 groupname userlist\n"
exit 1
else


echo "The following users do not exist in the directory" > ./non_existant_users.txt
group="$1"
userlist="$2"

echo "Adding users in $userlist to group $group"

read -p 'Enter username with directory write : ' admin
read -p 'Enter password for user : ' -s password

#echo "test user: $admin, test pass: $password"
echo "group: $group, userlist: $userlist"

for user in `cat $userlist`; do
	if ! id -u "$user" >/dev/null 2>&1; then
		echo "User $user does not exist!"
		non_existant="$non_existant $user"
	else
		exists="$exists $user"
	fi
done

for isuser in $exists; do
	#dseditgroup -o checkmember -m $isuser $group
	dseditgroup -o edit -n $dirnode -u $admin -P $password -a $isuser -t user $group
done

for nonuser in $non_existant; do
	echo $nonuser >> ./non_existant_users.txt
done

fi

NAME

       rbash - restricted bash, see bash(1)

RESTRICTED SHELL

       If  bash  is  started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted.  A restricted shell is
       used to set up an environment more controlled than the standard shell.  It behaves identically to bash with the exception that the  follow-
       ing are disallowed or not performed:

       o      changing directories with cd

       o      setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV

       o      specifying command names containing /

       o      specifying a file name containing a / as an argument to the .  builtin command

       o      specifying a filename containing a slash as an argument to the -p option to the hash builtin command

       o      importing function definitions from the shell environment at startup

       o      parsing the value of SHELLOPTS from the shell environment at startup

       o      redirecting output using the >, >|, <>, >&, &>, and >> redirection operators

       o      using the exec builtin command to replace the shell with another command

       o      adding or deleting builtin commands with the -f and -d options to the enable builtin command

       o      using the enable builtin command to enable disabled shell builtins

       o      specifying the -p option to the command builtin command

       o      turning off restricted mode with set +r or set +o restricted.

       These restrictions are enforced after any startup files are read.

       When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
