Backticks are old and some shenanigans can happen with them and they are still there only for backward compatibility afaik.

To be fair, that's most of Unix and computing in general.

Personally, I think backticks are cooler and I usually go for them first, and then switch to $( ) when I need to nest something.

--- Quote from: jrgp on June 10, 2021, 01:28:22 am ---Instead, why not find a way to pass netcat's stdin and stdout to your script's stdin and stdout, and operate on incoming lines as you receive them, using `while read line` or similar? That way you aren't busy waiting (as each loop iteration will block on reading an incoming message), won't drop messages, and will consume far fewer resources.

I have done what you suggested and seems to be working well. As a side note, since netcat cannot run programs within a socket, I had to use socat to attach stdin and stdout to the script. Busybox's netcat and Nmap's Ncat are two other options, but I did not opt to use them, since socat is more of a complete, advanced tool and I'm mostly used to it.
I will upload the sources to GitHub as soon as I reimplement the other scripts (have reimplemented only rcon_commands as of now).

NEW: Ported to C Shell. (Still need to work on rcon_kills and rcon_commands.)
[As of now, all scripts have been ported.]

The C Shell is powerful, more reliable and suitable for this project.
The code relies in the same repository, but in a new branch.

BlackFire533:
Some might wonder, "Why C Shell?"
Various reasons: C-like syntax, better built-ins, better scripting, a rich set of mathematical and logical operators, many convenient features (auto-correct, history substitution, built-in math).
It's also very secure; being "limited" makes it secure. (E.g: Nesting is minimal, thus preventing Shell injections at all costs; there are better ways to achieve what one want.)

The C Shell teaches how to safely write scripts. It's very cool. :)
The limitations aren't drawbacks.
