SYNOPSIS

822headerfilter prog

DESCRIPTION

The 822headerfilter program reads an 822-format email message from standard input. It executes prog with the header of the message on standard input.

The end of the message or the first line that cannot be part of an 822-format header field terminates the headers.

EXIT STATUS

If it encounters a permanent error in reading input or executing prog, 822headerfilter exits 100. If it encounters a temporary error in reading input or executing prog, 822headerfilter exits 111. Otherwise, 822headerfilter yields the same exit code as prog.
