The output of this script is shown below. The script needs to match the output, meaning there are errors in the current script that is not outputting what is desired.

There are four (4) problems with this script. Below is example output of the script:

./4-case.sh usage: ./4-case.sh ./4-case.sh start Starting process echo $? 0 ./4-case.sh stop Stopping process ./4-case.sh restart Restarting process ./4-case.sh reload Reloading process ./4-case.sh magic Unrecognized command magic echo $? 255

---------------------------------------------------------------------------------------------------------

The script that needs to be adjusted to meet the output:

#!/bin/bash

if [[ -z $1 ]] then echo "usage: $0 " exit -1 fi

case "$1" in 'start' ) echo "Starting process" ;; 'stop' ) echo "Stopping process" 'restart' ) echo "Restarting process" ;; 'reload' ) echo "Reloading process" done exit 0
