If your requirement is to schedule your script to run each hour (24 times a day), then below setup is correct:
Code:
00 * * * * ksh myscript.ksh > /dev/null

But if you wan to run it only between 9:00 AM to 11:00 PM:
Code:
00 09-23 * * * ksh myscript.ksh > /dev/null

OR
Code:
00 09,10,11,12,13,14,15,16,17,18,19,20,21,22,23 * * * ksh myscript.ksh > /dev/null
