Last night I was trying to burn CDs. Being annoyed with k3b and choosing to use brasero instead, I went to remove k3b. I typed in:
sudo apt-get remove k3b
I hit tab twice and saw that I had both k3b and k3b-data on my system. Assuming that I wouldn't need k3b-data on my system without k3b, I wanted to remove it as well so I typed in:
sudo apt-get remove k3b*
Unfortunately I hit Y to confirm without looking. It uninstalled a whole lot more than k3b and k3b-data. It uninstalled packages which did not fit my "k3b*" regex. For example: transmission and network-manager
I'm fairly certain that I didn't have a space between k3b and * but I don't know why else it would remove all that it did. Is there something about apt-get that I'm misunderstanding?
