Used dd command with no options
 

Hi guys.
I'm very scared.
I was in the CLI experimenting with lynx and then i thought hmmm let's see what this dd thing can do and usually when i run commands without parameters just gives me an brief idea about what can i use.

With dd it just hangs on there like it would be doing something ...

I immediatly quit that terminal and then i couldn't mount my ntfs big important lifesaver partition . I rebooted and now i can . I just want to ask what damage could dd make if run without any parameters ...

I'm so worried .. I don't have any external backup medium.

Hmm... I dunno. I've done that a few times before and nothing bad happened. TBH, though I could be wrong, I don't think anything happens since dd has no input or output targets given.

From the man page:

So, dd without parameters should behave like cat without parameters: dump stdin to stdout. It seems to hang because it waits for input forever, which it doesn't get.

You really should.

thanks . i undeerstand ..

*starts crying*

No need to cry, no harm done yet :) . But let me quote a signature I once read somewhere: "There are only 2 types of users. Those who do backups, and those who never had a harddrive fail."

i guess i'm the second type :)

[solved]

I never do backups... lol.

that's because you use a MAC :P

this thread is really going offtopic .. maybe someone could close it :)

How is... What does... What do... I don't... Why is... Why... What? Is there something special about OS X that I don't know about? Lol?

I just don't take backups because I don't really have too much on my computer in the first place. To be honest, most of my stuff can easily be re-downloaded from someplace on the 'net in a few hours or so.
