Top Forums Shell Programming and Scripting Iterate over `dirs` in a bash script Post 303033133 by RudiC on Saturday 30th of March 2019 01:29:06 PM

Please become accustomed to provide decent context info of your problem.

It is always helpful to carefully and detailedly phrase a request, and to support it with system info like OS and shell, related environment (variables, directory structures, options), preferred tools, adequate (representative) sample input and desired output data and the logics connecting the two including your own attempts at a solution, and, if existent, system (error) messages verbatim, to avoid ambiguities and keep people from guessing.

Where are you stuck? Running your given script yields
Code:
Key:  /home/myuser 
Key:  /etc 
Key:  /usr/local 
Key:  /usr

on my system. Even the exotic ${arr[$i]+7} doesn't give an error message (but doesn't evaluate to something sensible either) .
