util-vserver:Bash Completion

2014-02-07T07:32:06Z

Rbe:

To test this, put the source in your .bashrc or put it in the file /etc/bash_completion.d/vserver (Debian).

This release (0.4) supports the commands vserver vapt-get vrpm vyum vserver-copy.

This script is included in the util-vserver Debian package, and is automatically installed into /etc/bash_completion.d/vserver when you install this package.

For zsh completion, the Debian zsh package has the vserver completion included, see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=365238 for the source, or https://intrigeri.boum.org/svn/pub/home/modules/base/.zsh/functions/_vserver for the upstream SVN repository.

# Completion for the vserver command. Source this file (or on some systems
# add it to ~/.bash_completion and start a new shell) and bash's completion
# mechanism will know all about vserver's options!
