Hooray, a bike shed for a rainy day.
Enough theory. Here's all you need:
Pick one, start at the beginning, work your way through. (You can
read those three books online for free, if you need to. And use the
linux advice, it's basically the same as FreeBSD.)
I have learned perl to expert level 3 times in 20 years.
(there's a clue in there about how much I like perl)
I spent 10 years writing all my scripts in ruby.
I made quite a bit of money writing c, c++ and fortran.
I can write bash expertly too. But any reasonably sophisticated bash
program ends up looking as transparent as a medium level perl
program. I.e., inscrutable.
I taught myself go, and it's very cool, for a kid's language. I wrote
a "configure" type front end to cmake in bash, perl, and go as an
exercise, and the go version is by far the most transparent, while
needing 25% less code. But the size of the binaries, egads. OTOH,
given the whole container religion is being built with it, you can
probably get a job easy. While the buzz lasts. The docs are very
Nowadays I just write in c++14. Everything. It is bliss. But I've
been c++ templating since 1991. Having witnessed the insane variety
of f*cked up c++ projects though, I can't recommend it to a beginner.
