Reset to default

That means if you input fix-permissions.sh user1 user2 user3 on the command line, your script will process these 3 users. In your script, you go through these arguments using $@

eg

for u in "$@"
do
  echo "$u"
done

please see man page on POSITIONAL PARAMETERS for more information

Actually, in that case bash permits you to omit the in "$@" -- it will assume that if it doesn't see in <anything else>.

Positional parameters. $1, $2, $3, $@, etc.
