Top 20 Concole Commands

[cbfunky]

Hi,

what would you consider your top 10 or top 20 commands that you consider mandatory to know when working with the shells?

[mrBen]

Hmmm tricky. I'm just a newbie, but here are some that I use the most(in no particular order) :

ls
rpm (if on Mandrake), or
apt-get (if on Debian)
tar
chmod
shutdown -h now
su
cd
mount
vi
startx :p

[Gray_Race]

I can tell you my least favorite.

rm -rf /

[jscott]

logout being the most important...

Just a note to any cluless newbies (not pointing at anyone in particular) This command is a "Very Bad Thing"...don't run it :D

Don't run it as root. This is a prime example of why you should use the root account only when needed!

Actually, I never use logout. exit is aliased to it for me, so I use that - it's shorter :)

20 in no particular order:

ls
cd
more
grep
find
which
cat
echo
sudo &lt;something&gt;
aptitude (though this is just a keybind for me now)
vim
ssh
ncftp &lt;hostname&gt;
w3m &lt;url&gt;
startx
awk
df
free
top
ps(tree)

Did you actually use that once??

Exactly...one mystype ("rm -rf / home/user" will produce the same results as "rm -rf /") can whipe your whole system (including any windows partitions you have mounted) with one command. Never run as root unless you need to for somthing

[cbfunky]

doesn't "halt" do the same thing?

[Gnu/Vince]

ls
cd
grep
vim
ps
top
w
uname -a
cat
cp
mv
rm
ssh

[Gray_Race]

Thankfully no, but I've heard many a horror story.

Just for people who don't know. If you run that command as root, you will delete everything on your hard drive. The -r means that it is recursive, going through every directory, and the -f means it will force it, do it all without any prompts. Only way to stop is ctrl + c and you'll still lose some information based on how fast you press the buttons, so don’t run speed tests. :(

[Strike]

can't forget:

cowsay
(and now) figlet (GnuVince's find)

[cbfunky]

Ok, these two I couldn't find, what do they do?

And for all those worried faces: I surely won't execute an unknow command (which (what a surprise!) wasn't even the case here) without consulting some manpages first.
I might be stupid, but I'm not THAT stupid
:p

I knew you wouldent...but there are others out there who would.

Cowsay prints out a ascii cow who says somthing in a voice bubble...don't know about the other one though.

[recluse]

Umm
apt-get social-life-1.0 , never acutually tried it but if it worked it could be fun, though it would be quickly followed by a
dpkg --remove social-life-1.0
seriously I like
less
top
find

[jbstew32]

chmod
grep

su
pico/nano (whatever is available)
rm

find
shutdown -h now
make
installpkg
removepkg
upgradepkg

:cool: Slackware :cool:

[cbfunky]

This is not fair, I tried cowsay in every shell I know (which aren't that many but whatever), and it didn't work :( .
Might this be distro specific??

I want to see that cow!!

Try a google search for it. It normaly doesn't come with a distro.

[slacker_x]

nobody has mentioned "du" yet. I use that quite a bit.

[nick098]

my most used commands are:
cd
-and-
..
and my least favorite is:
rm -rf /
but my favorit in dos is
format c:

[twofoolish2b]

gawk, date, finger, wait, unzip, touch, nice, suck, strip, mount, fsck, umount, make clean, sleep. :D

[cbfunky]

ok, I downloaded that cowfile, but how do I unzip *.deb files if not on a debian system?

[Derango]

You probably need a program called Alien, that converts betwen package formats. It might be installed already...if not, try google again ;)

[cbfunky]

Using alien gives me A LOT of error messages

hmmm...maybe someone else can help you then, I'm not too familiar with alien.

Try here for a tar.gz file of cowsay

ftp://ftp.nog.net/pub/tony/cowsay/cowsay-3.03.tar.gz

[Strike]

Recipe for using deb's on a non-Debian system (with the additional note that deb's were designed so that ANY Unix system could use them, though only dpkg/apt maintain the nice dependency database and all that):

1. ar x &lt;package&gt;.deb
This will create three new files: debian-binary, control.tar.gz, and data.tar.gz
debian-binary - seems just to be what version of the package system it uses or something like that. Mine simply contained "2.0" for a recent one. It's unimportant for this type of extraction though.
data.tar.gz - the meat of the application, all of the data files for the program are in here, and this will be what most of the size of the deb is made up of
control.tar.gz - pre/post-installation/removal scripts, md5sums, a list of config files, and the file that describes the deb (control)

2. mv data.tar.gz /
All the paths in data.tar.gz are relative to the root directory (because they are made using fakeroot), so we want to move it here before extracting

3. cd /
Get into the root directory, duh.

4. tar xvfz data.tar.gz
You might skip "v" on this one for big packages, because it lists the files being extracted.

And, you are done. It is installed on your system, so to speak. You might want to unzip control.tar.gz (tar xvfz control.tar.gz) and take a look at the pre/post-installation scripts to see if there's anything that needs to be done. Or you can just extract them and run them.

Heh!

[Gray_Race]

Cowsay is fun, but if you want to go simple, without downloading anything just type in:
fortune

And it will tell you the meaning of life. hehe

[Cheeves]

well lately its been hformat /dev/hdc5 -- dont ask

I found a couple of codelines in some config file a couple of days ago that said "remove # if you want fortune" or so, and so I did.
However, fortune isn't working either.

EWO, that command wouldn't do anything ... I think you either mean

or

tar cvzf file.tar.gz directory/

Why wouldn't the other one work? I tried it and it worked fine.
Well, yours work, too, but I didn't get any errors with the first one. Or did I just do something bad to my system :eek: ?

"gawk, date, finger, wait, unzip, touch, nice, suck, strip, mount, fsck, umount, make clean, sleep"

I just got that, I so need a shirt that says that... ;)

[optech]

well, i don't really have many FAVORITE commands...
there ARE however commands i use often, but i don't like them... they're mostly system commands (ls, cd .., rm -rf, mount, ifconfig)...
but i DO have some commands that are only for kicks...
such as:
cat /dev/urandom &gt; /dev/dsp (favorite)
mpg123 Fear\ Factory\ -\ Linchpin.mp3 (from the office when i know that there're like 4 people near my home computer and my stereo is up loud.. hehe... scares the piss outta them)

[slapNUT]

kill

[slapNUT]

You ever notice how that pesky index.dat in the \windows\cookies folder is
nearly impossible to delete.
Here's part of my .bashrc

&lt;--snip
alias wipe='rm -f'
alias go='mount'
alias flush='umount'
potty=/win/c
butt=/win/c/windows/cookies/*

export potty butt
&lt;--snip

So if I get the urge to crunch that cookie index.dat I do this:

go $potty
wipe $butt
flush $potty

Actually anytime I mount my Bill Gates partition do some dirty deed then
umount it:

go $potty
do
dirty deed
done dirt cheap
flush $potty

hehehe
