The command to delete a user is userdel(8).

Please read the manual page for the command. It tells you the requirements and limitations for the command. It is the only way I'm aware of to delete a user, excepting a radical thing like reinstalling the OS (not recommended).

To use userdel, you need to be root. So, the only way I see is to do a script which use /etc/passwd to get the username from the uid. Then call userdel with the username found.
But I don't understand the requirement of UID use.

An example script

Code:

lookup=4711
username=`getent passwd "$lookup" | cut -f1 -d:`
if [ -n "$username" ]
then
  echo "running 'deluser $username'"
  deluser "$username"
else
  echo "$lookup not found"
fi
