sudo chmod /dev/* screwup
Posted: Sun Jun 03, 2012 4:05 pm
So, I was trying to get this dvb device working. One suggestion was to change the permissions of everything in /dev/dvb/adapter0. I'd already tried sudo chmod a+r * and that did nothing. So later I tried "sudo chmod a+w *". Then I realized I'd run this command, though not the others, in /dev, not /dev/dvb/adapter0!
So, how can I fix the permissions in /dev back to the way they were? What were they to begin with? Or, at least, what are the essential devices to turn write permission off on?
Edit: I should mention that I'm on the XFCE edition of LMDE.
Edit2: Well, a reboot did wonders. The following are the only non-links that currently have global write permission in /dev are:
Any of those that shouldn't?
