clientDIR=0
backupDIR=0
clientFile=0
backupFile=0
dateStamp=0
saveLocation=0

#1. Create client file:
clientDIR=/home/[USR]/
dateStamp=`date +%d-%m-%Y`
saveLocation=/home/root/scripts
clientFile=$saveLocation/clientFile@$dateStamp.txt

cd $clientDIR
for i in "$clientDIR"
do
       ls -lstR > $clientFile
done

#2. Create backup file:
#ssh to offsite backup location using key rather than pw
#backupFile=insert ssh login without pw using key to ip + /backupFile@$dateStamp.txt

#TEMP TEST FILE
backupFile=$saveLocation/backupFile@$dateStamp.txt

cd $clientDIR
for i in "$clientDIR"
do
        ls -lstR > $backupFile
done

#3: To compare files:
#cmp <- Compare two files
#Not working

#comm <- Compare two sorted files line by line
#Not working

#diff <- Display the differences between two files
diff -y $clientFile $backupFile > $saveLocation/diffOutput@$dateStamp.txt
#diff command doesnt recognise files due to order....

#4: If:
#       a) A has a file B doesn't < Warning report
#       b) B has a file A doesn't < Mark for deletion
#       c) A has a modified file to B < Warning report

#5. Do the following:
#       -i < Identify / Create a report with what would have been deleted

#6. If no restriction is placed then delete.
