Return command in a shell script

Chartier Jerome — Tue, 21 Jan 2003 15:04:13 GMT

Hello,

Is there an equivalent command for the return command in HP world. I'm trying to debug compaq scripts to work on HP, but a return command doesn't work (it's normally going back in a loop and do some tests).

Thanks in advance

Regards

I don't understand your question. HP's POSIX and Korn shells have the return command and it works as advertised. Normally it is used to return a function result but if used while not in a function then it is equivalent to an exit.

What may be happening is that you are using a return in a sourced script
e.g.

. myscript.sh
within a parent script. In this case, the sourced script becomes part of the parent process and a return is then an exit.

Hi Jerome,

If you put a return code after your exit statement at the end of your code, you should be able to get that return code you are looking for.

If you want to test return code in shell script, you can do:

exit n ==> n is the number

To test:

if [[ $? = n ]]
then
...
fi

This test can be done by other shell script.
