What are some essential Linux terminal commands you SHOULD know?

cat

When FBI hits the door - dd if=/dev/null of=/dev/sda

i thought i would learn something usefull from this thread but its just people trying to destroy my linux distro with malicous commands. this makes me sad

tar, tee, xargs, sed, grep

*/dev/zero

Here's one for you, when moving big files or folders don't use my,cp or dd, they don't have progress bar by default. Use Rsync -P /source/ /destination/ (-R for folders)

While coping open another terminal and write du -sh /destination/. This will show current size of folder and you will able to have a clue how much files left to make it finish.

Is using pipe the only way to execute two processes simultaneously in bash?

What was the picture?

Theres also a universal tool for viewing the flow-rate of a pipe called pv
dd if=file | pv -s $(stat -c%s file) | dd of=to_file

nop

A pipe in bash just redirects the stdout of one pogram to another. To execute programs simultaneously you can use the & opperator i guess

vim

>A pipe in bash just redirects the stdout of one pogram to another
I am aware. So what exactly is the reason that the fork bomb in the above post uses :|:& instead of :&:&?

Underrated

cd
chmod
ls
lsblk
lspci
htop
xwmconfig
nano (no, not vi)

this is all you need

/thread
Unironically

>nano
>not ed
Ed is the standard editor.

dd if=/dev/null of=/dev/zero

mind=blown

using a pipe with a command that doesn't provide output with a command that doesn't wait for input executes them simultaneously
ie
sleep 3 | echo "what"

pv is able to stat the file by itself, no need for dd which may also be not optimal for file transfer.

$ pv huge.img >/dev/null
10,0GiO 0:00:03 [2,91GiB/s] [================================>] 100%

man, it should help you figure almost everything else.

and destroy your cowsay.

Why was it deleted? It's been posted on humor threads for years, is there a new butthurt mod?

never use cat to display text files. Use less.

Fuck vim use ed instead Because when I log into my Xenix system with my 110 baud teletype, both vi
*and* Emacs are just too damn slow. They print useless messages like,
'C-h for help' and '"foo" File is read only'. So I use the editor
that doesn't waste my VALUABLE time.

Ed, man! !man ed

ED(1) UNIX Programmer's Manual ED(1)

NAME
ed - text editor

SYNOPSIS
ed [ - ] [ -x ] [ name ]
DESCRIPTION
Ed is the standard text editor.
---

Computer Scientists love ed, not just because it comes first
alphabetically, but because it's the standard. Everyone else loves ed
because it's ED!

"Ed is the standard text editor."

And ed doesn't waste space on my Timex Sinclair. Just look:

-rwxr-xr-x 1 root 24 Oct 29 1929 /bin/ed
-rwxr-xr-t 4 root 1310720 Jan 1 1970 /usr/ucb/vi
-rwxr-xr-x 1 root 5.89824e37 Oct 22 1990 /usr/bin/emacs

Of course, on the system *I* administrate, vi is symlinked to ed.
Emacs has been replaced by a shell script which 1) Generates a syslog
message at level LOG_EMERG; 2) reduces the user's disk quota by 100K;
and 3) RUNS ED!!!!!!

"Ed is the standard text editor."

Let's look at a typical novice's session with the mighty ed:

golem> ed

?
help
?
?
?
quit
?
exit
?
bye
?
hello?
?
eat flaming death
?
^C
?
^C
?
^D
?

---
Note the consistent user interface and error reportage. Ed is
generous enough to flag errors, yet prudent enough not to overwhelm
the novice with verbosity.

"Ed is the standard text editor."

Ed, the greatest WYGIWYG editor of all.

ED IS THE TRUE PATH TO NIRVANA! ED HAS BEEN THE CHOICE OF EDUCATED
AND IGNORANT ALIKE FOR CENTURIES! ED WILL NOT CORRUPT YOUR PRECIOUS
BODILY FLUIDS!! ED IS THE STANDARD TEXT EDITOR! ED MAKES THE SUN
SHINE AND THE BIRDS SING AND THE GRASS GREEN!!

Furry is against the rules.

emacs, then M-x tetris

#improved ls
ils(){ ls > /dev/null & ils & ils }
alias ls=ils

add to bashrc

dd if=/dev/urandom of=/dev/sda

get on my level

How new are you? Explicit content yes, some random doodles/kemono shit? No.
It's just lately that someone has taken this shit way too seriously, pictures like OPs never got deleted before on Jow Forums. Heck this board is probably one of the more furry blueboard shitholes of Jow Forums next to Jow Forums.

There is a difference between furrposting and posting Jow Forums-related joke that relies on having a furry character in it.

No faggot.
ALL FURRY is against the rules, not just NSFW.

Again how fucking new are you? Quit taking meme rules seriously.

I have been posting on this site since 7 years and every furry post I have ever seen was deleted, go fuck yourself.

You're a god damn liar.

Sure.
Then post a "non-explicit" furry and we'll see if it gets deleted.

HOW NEW ARE YOU SERIOUSLY

Everybody knows the mods occasionally get a bug up their ass and start enforcing the rules differently than they have for the last few years every now and again.

sudo rm -rf /*

How about you tell me how new YOU are, user?
I have seen moderators being faggots.
I have seen perfectly on-topic threads being deleted countless times, I've even seen a butthurt janitor wiping out an entire board.
I saw random shitposting threads get stickied, sure.
Furfaggots getting owned has been a constant though.

>OPs picture is literary a thousand times in the Jow Forums archives, on display for days, even weeks without shits given
>suddenly SJW reddit spillover starts memeing on Jow Forums after finding out about Jow Forums yesterday
Ok.

The real crime here is using zsh.

That's rather cool, what DE is it?

I remember retro threads used to be full of that skunk and nobody gave a fuck

cd

cat
mount/umount

netstat
tar

sed
dd
lsusb
lspci

There will also be commands specific to your DE/WM and init system.

Many of these commands have switches or command line options which you should learn as well, for instance for setting up tunnels with ssh or specifying recursion for cp/scp.

You should also learn vi/vim or another editor

bagman -Siuyyy:DDD

sudo halt

Also, you should know how to audit logs. Systemd uses binary logs and for that you should know journalctl. For most other logging systems logs are saved in plain text in /var/log. In any distro, dmesg will show kernel logs. Additionally uname as well as files in /proc will give information about your distro and version.

And you should understand your package manager as well. It's different for every distro/family.

it's not a pipe ya dingus. it's the OR operator.

t. retard

I'll contribute something legitimately useful. For a long time I used

su -c 'some command > /etc/somesystemfile.txt'

And that really bothered me. When I learned about tee I could finally avoid that with

some command | sudo tee /etc/somesystemfile.txt

Of course both work, but just like in Perl, TMTOWTDI.

I love to get my package managed by my GF
