get-header - extract a header field from a mail message or news article

SYNOPSIS

get-header [ -f ] [ -i ] [ -w ] fieldname [ default ] < message

COPYRIGHT

DESCRIPTION

Get-header reads from standard input the header (up to the first blank line) of a mail message or news article. It looks for the first occurrence of the given fieldname. If found, it writes the value to standard output. Otherwise, if there is a default value it writes that.

OPTIONS

-f: Assume the field is an address field, e.g. a From: field. Try to find the full name, using msgfn(3).
-i: Ignore case (upper or lower) of the field name.
-w: Strip leading spaces and tabs before writing the value of the field.

EXAMPLE

To print the subject, or "none" if there is no Subject: field:

   % get-header -i subject none < message

Get-header could also be used to pull fields out of very simple data files, e.g.
