Understanding the IFS in Bash! Stringify Arrays easily - You Suck at Programming #030

i suck at programming because you always teach scripting

use ${a}. My goodness. Do I need to teach you how to bash? Jokes.

You do have a channel name that appeals to masochistic bashers(programmers?)

Bash has lots of features, that are anti obvious and obscure. IFS is one of those. Thanks a lot for brilliant explanation in a concise manner, that was great.

Why are you bully me? Just kidding, I really suck at programming, ty, sir. But tell me, please, what do you use to make videos, i.e. hardware (camera, mic) and software

Cool

echo "Bob;Alice;John" | while IFS=';' read a b c; do echo "$a + $b + $c"; done
Instead of
echo "Bob;Alice;John" | tr ";" " " | while read a b c; do echo "$a + $b + $c"; done

Bash is the only language that makes me wish I was working with Perl

This is really useful stuff, thanks. Bash can be weird but its in Linux and subseqeuently UNIX everywhere so we like it or no, we need to know it
