Some fun with the shell

[ilja]

Who knows interesting things?

I know this :
echo "[q]sa[ln0=aln256%Pln256/snlbx]sb729901041524823122snlbxq"|dc

[ghaefb]

Wtf is this ?? :)

[ilja]

man dc ;)

[jrblevin]

Turn your speakers up loud and try the command in my sig

cat /dev/random > /dev/dsp

[ghaefb]

yeah right :)

[Jman]

How many bogomips (http://www.tldp.org/HOWTO/BogoMips-2.html) do you get?

cat /proc/cpuinfo | grep bogomips

[fjleal]

5583.66

Is it good? What's a bogomip?... :)

[ilja]

bogomips : 4128.76

I have got less :(

See the link, which Jman gave above for explanation of BogoMIPs

I would advice you guys to stay far away from this one:

[ $[ $RANDOM % 6 ] == 0 ] && rm -rf / || echo "You live"

Russian roulette for nerds.

(ripped from bash.org, heh)

do NOT run it.

a friend of mine did before he actually saw what it did. he was.. mildly upset :P


//edit: I have made your post more colourful. I hope you won't mind ;) Ilja

Ilja: ah, not a bad thing, that :)

There used to be a whole web site for this sort of thing....linuxsucks.com or something
similar. Anyway, how about these...do NOT use them.

dd if=/dev/zero of=/dev/hda

cp /dev/random /boot/vmlinuz

chmod 777 /etc/shadow

iptables -j ACCEPT

[ilja]

No that's not funny. That are ordinary commands. It just damages your system.

[Jman]

Let's stay away from destructive commands, shall we?

/usr/sbin/lsof | wc -l
This one counts the number of open files on your system. Files can be regular files, sockets, network connections, the /proc filesystem... you get the idea. Everything on Linux is a file.

Note that it is a couple off because of the way lsof is formatted, but it's close enough.

[Jman]

This one's actually useful.

Let's say you installed a package but have no idea what the binary to run is. Chances are it is in some kind of bin directory, so rpm -ql package | grep bin will find it.

That reminds me of a post on another forum where one user advised another to place his WAN network interface in the "trusted zone" in a popular windoze firewall app as he couldn't access his shared drives :rolleyes:

Some people just irradiate stupidity in all directions :D

$ :(){ :|:&};:

PLEASE SAVE YOUR WORK BEFORE ISSUING THIS COMMAND
:D

[Ug]

I'm so very tempted to input it - but i'm gonna resist.

[ilja]

I've done it, it's so cool. I even had no chance to shutdown it :D
thx kosmosik

This one is safe:-

How about C style constructs in bash? Try this script:-
(( x = 100 ))
echo "x = $x"
(( x++ ))
echo "x = $x"

The double-bracket construct allows you to perform arithmetic functions instead of using let.
