To run a shell script automatically on time
I have a shell script named as Ping.ksh.Actually this script will ping 100 server for few second and suit a mail to me the server names those are not in online.
So i need to run this script 3am,4am and 5am daily. I'm new to this lunix. If you help me to run this job daily on above mentioned time interval that would be really helpful for me.
