NAME
header − extract fields from mail header
SYNOPSIS
header [-c] [-n] [-v] [-f fieldname] ...
DESCRIPTION
The header program reads a mail header on its standard input. Any text that follows the header is ignored. It then prints all, part, or none of the header to its standard output, depending on its command line options.
OPTIONS
|
−c |
Match field names only if their cases match. Normally, mail header field names are case-insensitive. | ||
|
−n |
Prefix displayed header fields with their names. The resulting output is itself a valid header (albeit possibly shorter). By default, only field values are displayed. | ||
|
−v |
Print only the fields that are not listed in −f options. |
−f fieldname
Display (or delete, if -v) header fields with the given name.
