UNIX for Dummies Questions & Answers

On my tests with ksh the "scripter.online" approach does not work.
Though exporting VAR_A makes the variable visible in the called script b.sh, the changed value of VAR_A is not available to the calling script a.sh .

I have certainly used the approach suggested by "chompy" and written results to a file and then read them back in the calling script.

If b.sh is normally silent there are a couple of ways of passing values back.

Code:

General solution where the reply is a word or a number

From a.sh
b.sh | read REPLY

In b.sh
echo "whatever"

Code:

Another solution if the answer is a low number which is valid in "exit"

From a.sh
b.sh ; REPLY=$?

In b.sh
exit $value

i used bash for the above mentioned ..its working
