1. Get input from user
   cat <<EOF
   This script backs up the /home/$USERNAME directory to /backup, as well as any files and directories you specify here.
   Type the name of a directory or file name you want to back up, then press enter.
   Repeat for each directory or file name you want to back up.
   When done (or if you do not want to back up additional files or directories) just press Enter.
   EOF
   read DIRECTORY

1. Check if $DIRECTORY string is non-zero
2. (if it is, user pressed enter as first action)
   if [ -n “$DIRECTORY” ]
   then
   while test -n “$DIRECTORY”
   do
   TOBACKUP[$counter]=“$DIRECTORY”
   ((counter++))
   DIRECTORY=""
   read DIRECTORY
   done
   fi

1. Back up the directories entered by user
   for i in ${TOBACKUP[@]}
   do
   echo -e “Backing up /home/$i to /backup/”
   rsync -av —no-whole-file $i /backup > \
   /backup/backup-log_"$NOW" 2>/backup/backup-errorlog_"$NOW"
   done

1. Send log files via mail to user
   if test “$?” -eq 0
   then
   mail -s “Backup successful” “$USER” < /backup/backup-log_"$NOW"
   else
   mail -s “Some error occurred during backup” “$USER” < /backup/backup-errorlog_"$NOW"
   fi
   date
2. The same, a bit more complicated:
   #for ((i=0;i<${#TOBACKUP[@]};i++))
   #do
3. echo -e “\nBacking up ${TOBACKUP[$i]} to /backup”
4. rsync -av —no-whole-file “${TOBACKUP[$i]}” /backup #done
