hi Bipin,

thanks forthat.

I initially try to do it in my dev server without doing an ssh.

here is what I get..can you help?


Code:
./test_new.sh: line 4: ls /home/sendhabh/trial.done  2> /dev/null : No such file or directory
File not found.
-sh-3.2$ ls /home/sendhabh/trial.done
/home/sendhabh/trial.done
-sh-3.2$ wc -l ls /home/sendhabh/trial.done
wc: ls: No such file or directory
1 /home/sendhabh/trial.done
1 total

and this is my script:

Code:
-sh-3.2$ more test_new.sh
 #!/bin/ksh
while :
do
        if [[ $( "ls /home/sendhabh/trial.done  2> /dev/null " | wc -l ) -ne 0 ]]
        then
                echo "File found."
                break;
        else
                echo "File not found."
                sleep 10
        fi
done
