$ USER_NAME=$USER sh try.sh
$ cat try.sh
echo $USER_NAME

$ sh try.sh $USER
$ cat try.sh
echo $1

$ sh try.sh
echo $USER

$ try.sh -u $USER
$ cat try.sh
#!/bin/sh

while getopts ':u:' options; do
     case $options in
         u)
             user=$OPTARG
             ;;
         *)
             printf "Error: option %s not recognized at index %s\n"
$OPTARG $((OPTIND-1)) >&2
             exit 1
             ;;
     esac
done

shift $((OPTIND - 1))

echo $user
