21.5. Remove Mail/News Headers with behead
When you're saving or resending a Usenet article or mail message, you might want to the remove header lines (Subject:, Received:, and so on). This little script will handle standard input, one or many files. It writes to standard output. Here are a few examples:
mail Section 1.21
% behead msg* | mail -s "Did you see these?" fredf
Here's the script, adapted a little from the original by Arthur David Olson:
Go to http://examples.oreilly.com/upt3 for more information on: behead
#! /bin/sh case $# in 0) exec sed '1,/^$/d' ;; *) for i do sed '1,/^$/d' "$i" done ;; esac
The script relies on the fact that news articles and mail messages use a blank line to separate the header from the body of the message. As a result, the script simply deletes the text from the beginning up to the first blank line.
