Get container ID from inside an OpenVZ container

The following snippet will get you the OpenVZ container, when you're in a container. I have added this to my zsh prompt, but this might be useful in other places, too.

Code:

# Get OpenVZ container ID (/proc/bc is only on the host):
if [[ -f /proc/user_beancounters && ! -d /proc/bc ]]; then
  CTID=$(sed -n 3p /proc/user_beancounters | cut -f1 -d: | tr -d '[:space:]')
fi

Du bekommst damit die ID des Containers, in dem Du Dich gerade befindest ("virtueller Rechner").
ZSH ist eine Shell, so wie Bash, aber weitaus angenehmer.
