ITT we Post useful scripts

#!/bin/bash

[ $1 ] && [ $2 ] || { echo "usage $0 <file_type> <link>"; exit; }

wget -r -H -np -nd -e robots=off -A $1 $2

download files (like .webm) from pages (like /b/)

alias fuck=(sudo !!)
or sth like that

Is it possible for a script to use sudo so when you run it you dont have to type the password?

function weather()
{
    s=-37
    if [ -z $2 ]; then
        s=-7
    fi
    w=`curl --silent http://wttr.in/$1 | head $s`
    echo "${w}"
}

weather - current weather (auto location)
weather location - current weather for specified city
weather location x - 3 day weather for specified city (x can be any string)

shopt -s autocd

>>56669466
You can if you add your user to the suoders file:

visudo

Stop reading there.

How long did it take for you guys to learn bash? Is it big like any other language?

>>56669935
poo

>>56669944
>implying ``we'' don't know the bare minimum basics then just Google or go to ExpertSexChange/StackExchange when we need to do anything beyond while loops or basic comparisons

>>56669944
It didn't take long, less than year. There's a lot of quirks in the language and the sooner you start using something like Python or Perl instead the better off you'll be.

>>56669962
I guess I wanted to believe.

>>56669984
>>56669962
Also this.

Python/Pearl can replace bash and do same things on your machine? I dont understand what you meant by your post sorry

>>56670046
dude what? i was asking you fucking reading comprehension autist

>>56670027
Pretty much, yeah. Bash has a lot of quirks/edge cases that tend to trip up newbies. It also suffers from the fact that distributions don't always ship the latest/same version (OSX notoriously ships a really old version of Bash for licensing reasons).

Python (more than Perl) is a really consistent language and the chances of you running into some bizarre behavior is minimal. It's considered a "batteries included" language so you get a lot of functionality out of the box (json, xml parsing, http requests, OS operations like creating files etc).

>>56670088
You are the actual autist that cannot notice you used the word Pearl when you meant Perl.

>>56670089

Learn bash + C it's really only what you need.
Might want to learn Perl besides or you'll go the python route

>>56670156
In the long run, is it still better to go with Python since you can do broader range of different things with it, in different areas I mean(like web for example), because I understand that bash is limited only on *nix platforms?

>>56670199
Depends what you want to do honestly.
You can use any language but if you like python or Perl then use/learn those

>>56670199

Not the anon you're talking to, but python is definately useful as a general purpose language. I even substitute bash with python scripts in certain cases, since it's easier for portability.

>>56670199
Yes.

Python has a broader base of support these days than Perl (although Perl still has an active community). It also has a strong scientific community so if you eventually want to get into ML, NLP, or the hard sciences then Python is a good skill to have.

Look up pandas, nltk, and scipy for examples

Why not just counter++?

Is bash still relevant outside server environments and alike?

And even then Python is widely used even in those areas because of it's libraries.

No trolling, seriously.

>>56671710
* bash scripting, my bad

>>56671723
Bash scripting (more accurately shell scripting) allows one to manipulate several separate programs. Python and the like can utilize libraries, sure, but libraries are often monolithic - you can't change what's in a library, and it can be hell trying to isolate a modified library (if you can modify it at all), whereas a modified binary can be plopped anywhere outside its standard location, and utilized at will.
