Who can tell me what this does?

[iago]

I know the answer, of course. 

"kill -9 -1"

[Vex3]

I can also tell you... but that would be no fun for everyone else.

[Ergot]

I don't know what -1 does, but I could take a good guess

[iago]

I don't know what -1 does, but I could take a good guess

What would that guess be?

[Eric]

It closes all processes owned by the user with a process ID greater than 1.  I had to Google the -9, only to find out that it was exactly what I thought it was.

[trust]

It closes all processes owned by the current user. The -9 is the SIGKILL signal.

[iago]

Good job!

And can you guess the effect of running it on my laptop before doing "man kill" to find out what -1 does?

Instant lock-up for the current user! Woo!

Next, this one's tougher, who can explain to me what this does when run in Bash?
:-(){ :|:& };:

[trust]

It can't be good cause none of those are smily faces. :|

[iago]

It can't be good cause none of those are smily faces. :|

haha

And by the way, _please_ don't try that out on my server if you have access

[Joe]

Alright, thanks for the warning!

[Ergot]

ergot@darkside:~$ :-(){ :|:& };:

Code: [Select]

That's basically what it does, but how?

[Vex3]

I will start these easy and get harder....
