Ps and args return correct value , but function (readconfig) does not return correct value!
Any idea?
First off: you do not provide your source code but only tiny (and may insignificant) morsels of it. You do not provide any output of the script but tell us only the absolute minimum of symptoms like "doesn't work" or "doesn't print". How are we supposed to debug your script on only rudimentary second-hand information?
And speaking about debugging: how about sitting down and put some debug statements into your code? At least you could show the same amount of effort you want to show us helping you in helping yourself!
Regarding your problem: i suppose the variables inside readvar() are local to that function and therefore the values are not usable outside of it. A shell function will not "return" anything else than a return code (an unsigned short short it).
Dear Bakunin,
You right
Here is the more detail , when I use “set -x” in “readconfig” function in code:
Here is my config file content:
Here is output of script after run with set -x in “readconfig” function.
The purpose of a function is:
it is defined once, and can be used multiple times.
In other words, the function definition should be once, before the loop, NOT in the loop.
Move it to the beginning of your script!
In the loop you call the function.
