Bash General

if [[ ! EXPR ]]; then
echo "Nobody writes if statements like that."
echo "Also, [ is POSIX syntax, not bash."
fi

All I write is bash since it's easy and I'm lazy.

You're much worse than that, yes. But you're still a faggot

because i'm using rc.

DESCRIPTION
rc is a command interpreter and programming language similar to sh(1).
It is based on the AT&T Plan 9 shell of the same name. The shell
offers a C-like syntax (much more so than the C shell), and a powerful
mechanism for manipulating variables. It is reasonably small and rea‐
sonably fast, especially when compared to contemporary shells. Its use
is intended to be interactive, but the language lends itself well to
scripts.

Bash is the most hideous scripting language to ever exist and I fucking wish POSIX would throw out sh and get something that's not shit instead.

"[" is a short way to write "test", that's why you need spaces.
Source: man bash, man test
Ps: correct syntax in bash is "[[...]]"

>syntax
it really is ass. Who the shit came up with this bullshit?

install rc

If your bash script has more than 2 if statements it’s time to switch to python.

If you have to stick with bash, at least use the shellcheck linter.

I've written a lot of BASH but I avoid it when I can. The syntax is disgusting

You mean GNUshit. Linux is a kernel.

remove the cat file
add done < file

also wget can read URLs from file

I'm very bad at it and I dont want people to Bash me B)

Rc is way better than bash. Most of the gnu stuff is trash

Wish I could stand the retard made GUI of linux's DEs. Windows just works, it's snappy, there's no blur.

I write my scripts in js and python because they're more modern

I write too much bash code. I need to fix myself.

bash is featureful enough that you can do an uncomfortable amount of main processing and logic with it, and your main issues will be speed and bash's nasty syntax
I should just use a different shell language, but bash is installed on damn near everything and if I'm writing in it, I'm already being a lazy shit

IFS=

would be nice if bash offered a no legacy mode that disabled most of the bullshit misfeatures it inherited from sh

bash isn't sh

both of them are 29 and 23 years old respectively.
what other kind of shit do you have as excuses?

because most of it's python

>excuses
nigger It's literally faster. I have written bash scripts too

Here POSIX mastercode:
[ ! EXPR ] && echo "wtf"

When someone says "bash" there's a big chance that it's due to ignorance and they just want to mean "shell script".

posix is cuckolding
why would you care that your script runs on macos or other shitsystems

>Why aren't you writing more Bash code???
Because I'm writing POSIX sh code instead

even macos ships with bash

because bash syntax is fucking ass

Because python, user.

Anything I can use that uses java syntax?

retard

Is fish superior, is it worth learning?

Why? Why should I use shitty bashisms to do stuff that can equally well be done by any POSIX-compatible shell?

I love bash for its speed and ease of use,
but it becomes very hard to maintain after few lines of code, that's why I now use Python to automate almost anything

I have to take the time to learn it, but the syntax seems to be awful.

Because POSIX is shit. Abandon it.

For automating terminal stuff, Bash is infinitely better than Pyshit

HNNNNNGH!!

Ruby scripts require at most 1/3rd the code, often less. Get with the times.

because I write it in JavaScript if its more than 5 lines, otherwise I write a fish function

This is garbage advice. If you're doing things that mostly hook together existing commands just wrapping what you're doing in subprocess or os.system does not magically make it better. In fact often it's worse. Now you have to execve() another interpreter.

Fucking pythonfags.

Old as fuck bash because Apple can't into GPLv3. Enjoy your lack of patches.

It's completely not worth learning. However, you should do whatever you want to do.

Just don't expect to go work somewhere and use that shit.

>spinning up V8 to automate things on the CLI

Jesus fuck jsfags are retarded.

>UNIX creators did
wow, what a bunch of mongrels

>Because POSIX is shit. Abandon it.
I can see the logic behind that but bash is just the same POSIX, except with additional even worse shit tacked on top.
POSIX shell is at least portable and available pretty much everywhere and doesn't require starting additional runtimes, which is something neither bash nor any other language like python can claim. Perl and python do come close because almost everyone has these, but the keyword is almost, whereas pretty much absolutely everyone does have some POSIX-compatible shell.

What's the point in learning a bunch of cryptic commands when you can just click your way through the task or write a Python script? Enjoy your shell script breaking every six months and working on only one OS.

Too bad your ability to overpay for underpowered shiny hardware hasn't given you the ability to write software that is useful and lasts for years.

That's what I use Python for, and I can run it on Windows too.

Ho, and btw, use Python, otherwise your bash scripts will quickly become a mess.

Wrote an installation script for my environment today so I never have to set it up manually again, wish I would have done this years ago.

take the naked pill, anons. security is an unwinnable rat race.

Any tips for a Linux beginner to get into scripting? I've configured my entire system but automating it with shell scripts seems a bit tough without Googling everything.

rate

sed -e "/./ =" $@ | sed -e '/./ { s/^/ /; N; s/^ *\(......\)\n/\1 /; }'

#!/usr/bin/env bash

set -e

links=( $( wget "$@" -qo /dev/null -SO - | grep -oE '

Why do people even use bash in $CURRENT_YEAR?

>interactive shells
zsh, fish
>scripting tools
plain sh, Perl, Python, Ruby, a thousand other full-featured scripting languages

bash was a handy tool in early GNU days, but now it's a shitty middle ground. The extra scripting features aren't needed anymore and it lacks the usability and features of a modern shell (and the extra bloat is a non-issue on literally any device made in the last decade).

Sorry user, the game's over.

Do I even want to know why this exists?

Python and incels win.

This example is still simple, and yet it's almost beginning to turn into a big pile of unmaintainable code.
But if you decide to be autistic until the end, way to go.

you don't understand basics of a language
you should not write a code in any language without learning it properly first, string interpolation/evaluation rules are the basics!
people blame the shell when they are just too stupid to understand that syntax is not the only thing that varies beetween languages
you should not expect every language to act the same, they serve different purposes and were constructed in a way to aid the user in solving the particular set of problems

linux is a kernel
