Top Forums Shell Programming and Scripting Bash question: working with an array of previously set variable strings Post 302927263 by hungryd on Monday 1st of December 2014 06:04:46 PM

i appreciate the quick response!

if the range command (which i'd never heard of) is more effective at passing a list of values than the array command, why bother using the array command? it certainly seems like range is able to accomplish what array can do and then some.

the script works as i'd intended now, so to both of you, again: thank you.
