Assignment

For this assignment, create a script that will accept a working directory as the one argument. The script must:

• Create the directory if it does not exist
• Create an output file called output.txt in the working directory
• tar the output file into a file called output.tar
• gzip the output.tar file
• Move the output.tar.gz file into the directory the script was executed.

Details

• Try defining and using a function in this script.

Tips

• if [ -d $WRKDIR ] will check if a directory exists.

#!/bin/bash if [ $# -ne 1 ] then echo One argument expected. exit 1 fi WRKDIR=$1 function do_work { echo hello > "$WRKDIR/output.txt" tar -cvf $WRKDIR/output.tar $WRKDIR/output.txt gzip $WRKDIR/output.tar mv $WRKDIR/output.tar.gz . } if [ -d $WRKDIR ] then do_work else mkdir $WRKDIR do_work fi
