 Posted: Tue Nov 25, 2003 4:34 pm Post subject: How To _REALLY_ breakmygentoo! |
 |
|
Today I did a stoopid thing. I downloaded the binary package for OpenOffice-Ximian from breakmygentoo.net and then extracted it into my / directory. Not surprisingly it didn't work (I had one of those dumbass moments). So I typed: | Code: | for i in `tar -tjf openoffice-ximian-1.1.0.tar.bz2`
do
rm -rf ${i}
done |
And completely borked my gentoo. Much hilarity ensued.

Ouch. That'll leave a mark.
My advice is "don't do that"

See, if you had used a GUI, that wouldn't have happened!
And these people think CLI are better!

P.S. I am only kidding!!!! Don't flame!!!

How to (more) safely undo your tar...
for i in `tar -tjf openoffice-ximian-1.1.0.tar.bz2`
do
rm -f ${i} || rmdir ${i}
done
Do it twice. |

It won't quite delete everything, but it pretty much deletes any directory that the OpenOffice-Ximian tar put files into, which included /usr/bin among others  It also borked portage, so I couldn't just do a re-emerge of the system/world.
The rm -r means delete recursively, the f switch means force. Basically, if I'd just typed 'rm -r' it would have been fine(ish) - rm would have refused to delete non-empty directories. Adding the f forced to delete them without asking me first!
It's a pain, but in a way I'm glad because it means that I can reinstall Gentoo, applying everything I've learned since the last time I installed it!

Hmm, really? I was under the assumption rm -r would just try to delete everything recursively, whereas rm -rf would force it. |

I'm not sure whether or not you are being sarcastic, because that's what I said. In reply to Lews_therin, who asked what my commands would have achieved.
edit:
no, wait, I see what you're saying; the -f switch would force it to delete, say, write-protected files/directories. The -r will delete directories, regardless of whether or not they contain anything. I'm just trying to remember why I felt the need to add the -f... Hang on, I'll do it again
