Some Bits Of System Administration

… things that I found valuable or that I contributed myself

New and updated stuff

A simple colorize for the shell
postpone: A script to postpone some action for a given time

fullquoteremover: 2 simple scripts (Bash + AWK) to automatically remove full or excessive quotes from e-mail message replies.
However, please note that t-prot (the TOFU protection script) does a much better job, and is available as Debian packages. The concept behind fullquottel (by Philipp Spitzer and Gregor Herrmann) is more comparable to my own, though contrary to fullquoteremover, fullquottel is written in C++, and it comes with documentation. Lucio Chiappetti's approach uses procmail and awk just like mine but also removes HTML attachments.
