Unix Exit Codes

Asked by bowemc in KornShell (ksh), Linux, Shell Scripting

Hi,

I'm using a script to start my application on a daily basis. A cron-like application called Control-M calls this script at a give time and starts the app. The script istelf is very simple as you can see below.

However the line "Load app" occasionally has thrown an error which has resulted in "app.sh" failing to start up the applicartion. I need to check the "Load app" command has completed successfully before calling app.sh, otherwise abort.

How can I do this? Some one mention using exit codes, but I don't know how this works. any ideas?Start Free Trial
