I'd just like to interject for a moment. What you're referring to as Linux, is in fact, GNU/Linux, or as I've recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.

Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called "Linux", and many of its users are not aware that it is basically the GNU system, developed by the GNU Project.

There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine's resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called "Linux" distributions are really distributions of GNU/Linux.

info coreutils

The ones that are essential for whatever tasks you normally do...

Learn basic folder navigation like cd and ls, I guess. Not really essential when we have GUI file explorers though.

You just need three things to be self-sufficient:
- command line autocompletion. E.g. press 'a', then hit TAB twice
- --help. E.g. `ls --help`
- man . E.g. `man ls`
You can discover everything else by yourself with the above.
To give you a head start: ls, cd, echo, cat, touch, mkdir, rmdir, rm. IO redirection in shell is also very useful, e.g. `echo shit ass > muhfile.txt`

Halt

man

Those are gnu commands, senpai. He asked for linux commands.

grep, less, cat, head, tail, tee, awk, df, du, ls, dd. mount, umount

rm -rf /

>Lsblk

Lists drives

>Co

Copy

>Mv

Move, and rename if no path is specified

>Udisksctl

Allows you to mount/unmount disks, as well as other handy things

>Pushd

Move to a directory, then move back to original directory with popd

Touch

Make or update file

echo 'op is a fagg0t'

sudo rm -rf --no-preserve-root
sudo dd if=/dev/urandom of=/dev/sda

The ones i use pretty often:

sudo
cd
ls
cat
mkdir
mv
rm -r
cp -r
htop (you have to install it)
killall

Less used but still nice to use

mount // especially ISO mounting keys

What are the shortcuts for info pages?

This is essentially spam, i wish people like this were banned

That's a thing? I've always been using rm -r.

Just press CTRL+L

Don't forget pwd

sure
tho when I'm not too lazy, I like muh principle of least power

I forgot man and ln -s
The rest were just more-than-usually used things in a quick browse of my command history. There was no pwd actually.

sudo rm -rf --no-preserve-root

kill -9

this
also
sudo apt-get install gentoo -y

This, and grep

Tab completion, lsblk -a, cfdisk, vmstat.

It's education senpai.

Is there a command to search a file in all folders? Or should I just usr fsearch?

man find

Spam is free speech

locate

cat /dev/urandom
For that real hackerman cred

sudo pwd

cat /dev/urandom | hexdump -C | grep '12 34'

thanks for the neat tip. Been using "clear" all this time

> cat |
hexdump -C /dev/urandom | grep '13 37'

Inb4:

sudo rm -rf /

You don't need more user kun

dd if=/dev/zero of=/dev/sda bs=1M

man bash

tail -f /dev/log

apropos is arguably more helpful than --help as the latter is kind of redundant with man/info.

ls /bin /usr/bin

You're welcome

Seriously, the most important command you can learn is gdb.

what the fuck is a "linux command"

shutdown now

What's the command line equivalent of deletesys32?

What's a command that'll totally fuck my shit up beyond any hope of salvation save re-installation? Something only a bored retard would type in.

This makes 0 sense at all. You cant sudo dd or anything once you do sudo rm -rf --no-preserve-root /

# rm -rf --no-preserve-root /

If you are running a system with EFI, and have systemd installed on your distro, then the following:

rm -rf /sys/firmware/efi/efivars/

Systemd will happily wipe your bios for you. Have fun finding a way to reprogram the chips.

Wow. Why does such a command exist? I mean, what possible good reason would you want to do this?

Becuase SystemD needed to update some bios settings, and they decided to map the BIOS into the local filesystem, and if the files corresponding to the BIOS were removed, to wipe the actual corresponding data.

Damn. So if your comp has the trusty, old dependable BIOS rather than this UEFI shit, the command will have no effect?

apropos

Would this be affected by a rm -r /* --no-preserve-root then?

T-thanks Lennart

grep, wc, ifconfig, netstat, ls, chmod, chown, chgrp....


"cd -" is useful. It takes you back to the directory you were in previously.

"file" and "strings" are good, especially if you're into any sort of malware analysis/reversing

lsof is also good. If you want to know the PID of a process running on a particular port, you can do: lsof -i:

Use GNU/Linux, and there wouldn't be spam.

"Linux" is a colloquialism that your autistic ass needs to accept, because it's not changing no matter how much you bitch and moan.

Since GNU is called Linux, we can say that Stallman created Linux, right? And Torvalds created the Linux Kernel, which we can call GNU.

Linux is a kernel.

Fair.

Nobody's calling GNU Linux, they're using Linux as a term for operating systems that use the Linux kernel. Also, why does the credit stop at GNU? Why isn't it systemd/Freedesktop.org/GNU/Linux? The arbitrary line needs to be drawn somewhere, and like it or not, it already has been. It's just Linux.

What we say is that you ought to give the system's principal developer a share of the credit. The principal developer is the GNU Project, and the system is basically GNU.

If you feel even more strongly about giving credit where it is due, you might feel that some secondary contributors also deserve credit in the system's name. If so, far be it from us to argue against it. If you feel that X11 deserves credit in the system's name, and you want to call the system GNU/X11/Linux, please do. If you feel that Perl simply cries out for mention, and you want to write GNU/Linux/Perl, go ahead.

Since a long name such as GNU/X11/Apache/Linux/TeX/Perl/Python/FreeCiv becomes absurd, at some point you will have to set a threshold and omit the names of the many other secondary contributions. There is no one obvious right place to set the threshold, so wherever you set it, we won't argue against it.

Different threshold levels would lead to different choices of name for the system. But one name that cannot result from concerns of fairness and giving credit, not for any possible threshold level, is “Linux”. It can't be fair to give all the credit to one secondary contribution (Linux) while omitting the principal contribution (GNU).

>There is no one obvious right place to set the threshold, so wherever you set it, we won't argue against it.
Then stop whining when people choose to set the threshold at just Linux. When I say Linux, I don't mean operating systems with the Linux kernel and GNU coreutils. I mean operating systems that use the Linux kernel.

Such as Android and GNU?

Such as OpenWrt, Alpine, Android, Debian, OpenSUSE

You are referring to Debian GNU/kFreeBSD and Debian GNU/Hurd as Linux?

No, dumbass, I'm referring to the versions that use Linux as Linux.
