Another easy one...

Here's another one. What is an easy way to test if a user exists on a system? I want to test for a user's existence and then use that ID to chmod a directory. Thanks.

Hi Bobby,

There are quite a few ways like grepping the user from /etc/passwd, commands like logins, id etc.,. I use 'pwget'.

USER=Your_user_name
pwget -n $USER |grep -q "^${USER}:"
if [[ $? = 0 ]]
then
Your_chmod_commands
else
echo "$USER does not exist"
fi
