Top Forums Shell Programming and Scripting Terminate initially if error found... Post 302488058 by methyl on Friday 14th of January 2011 05:49:40 PM

Please show us how you run these scripts? Are you typing the commands at a keyboard? Are you using unix "cron"? Is there a wrapper script - if so, what does the script contain?

Code:
Script1.sh 
Script2.sh 
Script3.sh 
Script4.sh 
Script5.sh

Ps. As DGPickett implies you can indeed cause a sub-Script to exit with a non-zero exit status (e.g. "exit 2")which you can check in a wrapper script. Test the value of the variable $? on the line immediately following the invocation of the sub-Script in a numeric comparison. This is good scripting technique and not at all unusual. Confine exit codes to simple and low numbers because no Shell will allow a non-numeric exit code and many Shells cannot deal with large numbers in exit codes.

Difficult to suggest suitable scripting without knowing the possible values of $rc and knowing whether the variable contains a number or a string.


Ps. It always helps to know what Operating System and version you have and what Shell you prefer.
