Adding Content to Variable (bash)

http://www.unix.com – is this possible? its kind of like incrementing the value of a number in a variable. but in this case, instead of the value of the variable being a number, it's just contents/strings/characters/alpha-numeric etc. NOT a number. For instance: Code: VAR=Tommy for all in $(blah blah) do     VAR=($echo $all)     ###the variable $all can be any name .i.e cindy, sally, roy, matt done so at the end of the loop, i want the variable VAR to contain everything that was appended to it. So, if i were to do something like this after the for loop completes: Code: echo &q (HowTos)

In all my Googling, this usually happens when someone is comparing a variable, and that variable is unset.

in a bash script, How do I get a variable's content, from the contents of another variable, both variable names have the same trailing number?

IP1=192.168.0.17 DIR1=/mnt/2tb/archive/src/ IP2=192.168.0.11 DIR2=~/src/ IP3=192.168.0.113 DIR3=~/src/

I was using a fixed file extension and that was pretty easy to deal with in terms of accounting for variable cases (by using [Ff] &c within the loop).

However, I'm trying to allow the user to select the file extension.

Hello Community,

I'm quite confused about my current scripting issue... I source a file wich contains some variables, like "ks_name=Awesome". Then i echo some of the content, to verify its not empty, works...

But when i add multiple varibales together, the resulting variable is empty, eventhough i had added hardcoded text?!?

Here's the output:

Code: # | Fedora : Script
