rewriteheader

NAME

rewriteheader - replace strings in the message header

SYNOPSIS

rewriteheader [options] Headername Old New [Headername Old New [...]]

DESCRIPTION

rewriteheader replaces strings in the message header. It expect n times 3 arguments. The first is the name of a header, the second is the string to replace, the third is the new string.

Headername and old string are treated caseinsensitive.

rewriteheader expects the string to start and end at a word boundary. You can change to characters which rewriteheader treats as part of a word with the --wordchars option. rewriteheader will not demand word boundaries if you use an empty string as argument for the --wordchars option.

rewriteheader will only rewrite strings in the header. It only works as a filter.

OPTIONS

-w TEXT, --wordchars TEXT

See above. The default is: a-zA-z0-9@-_.=#$*

EXAMPLE

Example (utterly stupid): ( cat <<EOF To: me@host.example,someone_else@host.sub.example From: me@host2.example (me and only me) CC: nobody@example.example me@host.example Subject: test example

body EOF ) | ./rewriteheader subject example ""
                        to me@host.example me@otherhost.example                                 cc cc: bcc:  from "me and only me" "Me for my boss"

In case i screwed something up: short options use the same arguments as the long ones

SMALLPRINT

rewriteheader hates you. It will use every possibility to do bad things to your messages.
