Top Forums Shell Programming and Scripting bash - Variable made of variable Post 302392836 by Scott on Friday 5th of February 2010 04:19:11 PM

Hi.

I'm somewhat confused now as to what you're actually trying to achieve.

Code:
$ eval echo b$a
b4

Stop using backticks, and stop using the completely annoying expr commands.

Code:
k=$((k + 1))

Looking at your code, it looks like the eval is not the problem.

What is this all about?:
Code:
eval zo${k}=`awk -v k=$k {my_script} my_file`
