Shell Programming and Scripting

Hello Friends,

I am new to the scripting & have to analyze bunch of regular production scripts. It has .ksh which calls on the .awk script having many functions

I need to understand and debug the scripts ASAP

Can anybody please let me know as how can I debug, I want to see the flow of code to understand what is called after what etc..

Many Thanks,

-Amber

there is no debug mode in shell but you can see the values comming into variable and loop by executing it by

Code:

sh -x scriptname

or you can refer these manuals to understand awk
UNIX Utilities - awk
An Awk Primer
Advanced Bash-Scripting Guide

There are many programs available that will display script flow in a gui flow chart. I remember using one a long while back but I can't remember the name but it's similar to 'Visustin'. You might find others elsewhere. Once you breakdown the flow, then you will need to read as many awk tutorials you can find on the net because the learning curve is like '|' if you catch my drift.

Thanks for replies..

I am workking on a AIX box, is there any ways I can run the same scripts on my windows machine ?? anything which I can download and install on my laptop which will help me to execute and debug ...
