awesome,

I will try the exit 1. I tried that before but with just an exit in both else statements and I still had issues but will give it another shot. I will also add what you had suggested with the ping stuff, you made it clear that what I was doing wouldnt have worked as designed. Will let you know how it goes.

Regards

It appears to have worked except now when I do not specify "full or incremental, it proceeds to execute the "Full Backup" else statement instead of flagging incorrect syntax usage from my case area:

Code:
sudo ksh -x ./backup.ksh 
+ results=''
+ home=/home/testuser
+ backup_dir=/media/caca/extract
+ date +%m%d%y
+ date=102411
+ date
+ reg_date='Mon Oct 24 10:27:13 EDT 2011'
+ whoami
+ id_check=root
+ search=find
+ archive='cpio -oavc'
+ mail_to=me@testemail.com
+ sendto=/usr/bin/mutt
+ remote_host=192.168.0.32
+ ping -c 2 192.168.0.32
+ 1> /dev/null 2>& 1
+ ping_stat=1
+ (( 1 == 0 ))
+ echo ''
+ 1> /media/caca/extract/fullerror102411.log
+ echo ' Mon Oct 24 10:27:13 EDT 2011  ----------Full Backup Error Log----------                           '
+ 1>> /media/caca/extract/fullerror102411.log
+ echo ''
+ 1>> /media/caca/extract/fullerror102411.log
+ echo ' Make sure you are root and backup share is mounted on server **/media/backup_drive** '
+ 1>> /media/caca/extract/fullerror102411.log
+ echo ' The Full' 'Backup did not execute for one of the Following reasons:      '
+ 1>> /media/caca/extract/fullerror102411.log
+ echo ''
+ 1>> /media/caca/extract/fullerror102411.log
+ echo ' 1 - Ran as non-root user                                                 '
+ 1>> /media/caca/extract/fullerror102411.log
+ echo $' 2 - Share not mounted\t\t\t\t\t\t\t'
+ 1>> /media/caca/extract/fullerror102411.log
+ echo $' 3 - Incorrect Syntax\t\t\t\t\t\t\t'
+ 1>> /media/caca/extract/fullerror102411.log
+ /usr/bin/mutt -s 'Daily MYSQL Log' me@testemail.com
+ 0< /media/caca/extract/fullerror102411.log
+ exit 1

What should have been executed:

Code:
*)echo "Incorrect syntax usage. Use <backup.ksh> {full|incremental} or target directory does not exist. Please verify share exist";;

I no it the smallest little thing. I am missing something somewhere ??

I made another adjustment,fixed some of the logic and it fixed my issues. I created a pinger function and just called it when I needed it as opposed to using a variable constant:

Code:
pinger ()
{
remote_host=192.168.0.32
ping -c 1 $remote_host >/dev/null 2>&1
ping_stat=$?
}
##############

if [[ $id_check == "root" && -d $backup_dir &&  $results == "full" ]] ; then

                pinger

                if [[ $ping_stat -eq 0 ]] ; then
        cd $home
        ......

I also added exit 1's at the end of conditions

Code:
$sendto -s "Daily Backup Log" $mail_to  < $backup_dir/inc$date.log
exit 1
...

I will paste the finish product in a few.
