Simple if you can copy and paste into a file.

You can easily do this with awk, instead of sed
/bin/cat /etc/passwd | awk -F':' '
( $3 >= 1000 ) && ( $3 < 65534 ) {
print $1
}'
All of the users on a Debian system have UID >= 1000. For some unknown (to
me) reason, the user `nobody' has a UID of 65534 (or -1)
That will list the local users, no biggie. Lets complete the program then,
shall we.

{
cat /etc/passwd | awk -F':' '
( $3 >= '"$minuid"' ) && ( $3 < '"$maxuid"' ) {
print $1
}'
# We should probably take into account any NIS users.
if [ -n "`which ypcat`" ]; then
ypcat passwd | awk -F':' '{print $1}' 2> /dev/null
fi
# I don't know about LDAP...yet.
} | sort | uniq
------------------------------------------------------------
This will work (so far, on Slackware, Debian, and Redhat), with Local
accounts, and NIS accounts. More will eventually come...
Feel free to send me any updates.
