debug in a script function

lawrenzo_1 — Tue, 17 Mar 2009 13:03:11 GMT

Hi All,

I want to execute a script with ksh -x <script> so I can see the output of the commands however I would like to display what is happening with the functions of the script ....

does anyone know the syntax?

Thanks

Chris

put a set -x inside the function.

MI_FUNC () {
set -x
echo "lol"
}

the problem I have with that is the function is a check function ie

Check_Func () {

[[ $? -ne 0 ]] && alert

}

if I put the set -x in then $? always = 0

:-(

Thanks all the same.

Hi Chris:

> if I put the set -x in then $? always = 0

So do this:

Check_Func () {
typeset RC=$?
set -x
echo "I saw RC=${RC}"
...
}

Regards!
