Dear Raj & rest of my linuxer friends
Thank you for your efforts and help. I am pasting my code which gives me syntax
error unexpected end on line 17. Need help with why and correction? Am missing
something and cant figure out what?
Urgent help will be really really really appreciated.
-------------
if ! mount -t ntfs | grep /dev/sdc1 | grep /backup > /dev/null
then
mount /dev/sdc1
fi
if mount -t ntfs | grep /dev/sdc1 | grep /backup > /dev/null
then
#is a previous rsync process still running?
ps -ef | grep 'rsync' | grep -v 'grep rsync'| grep -v 'rsync.sh'>
/dev/null
if [ $? -eq 1 ]; then #rsync isn't running - let's launch it now
rsync -avz -e --delete /home/ /backup
else
echo "rsync is still running ...please wait and try again later"
fi
fi

Regards and thanks in advance.
