unix script for executing jar file thrice a day...

[Jigar Naik]

Hi,

I want to run MasterCard.jar file on 3 different time in a day on unix system.

and i have no experience in writing unix scripts.

can anybody guide me for the same.

i have gone through one thread : Writing unix scropt for executing jar file

and have created one file named cron.sh with the folloing script

  
#!/bin/sh
/usr/java/j2sdk1.4.2_12/jre1.4.2.12/bin java -jar /usr/local/lib/MasterCard.jar

Am i going on right direction ??? and what else i need to do ???

and how will this cron.sh get executed ???
one thing i'm wondering in this scriot is that there is nothing mentioned like everyday when to execute jar file.

I want my jar file to be executed thrice a day (10 AM,2PM and 6 PM)

do i have to mention this thing in script ? or unix command will execute cron.sh thrice a day ?

you are partially right and partially wrong....
partially right because you wrote a small file with the bash command you want to execute
partially wrong because you didn't use the CRON command

for a clear expaination check this like FOR SURE it will help
