Script function hierarchy

Gregg.JS · 12-29-2013, 08:55 PM

Dear experts,

Is there any way to view the call hierarchy for a /bin/sh script? Something like this might be useful to understand general flow. And also to know whether a function is being used or not.

Thank you,

It would be better if you can explain the question little more. However, you can run your script by adding set -vx (v stands for verbose, x for execution) debugging tool, so you can see every step of running script. To do this, just add it as:

Code:

#!/bin/sh
set -vx
.
.
Script content
.
.
