Re: check if message is in a particular sequence?

I'll shut up soon.

I thought I may as well create this and see if it gets used.

    $ cat ~/bin/mhinseq
    #! /bin/sh

    # Successfully exit only if the message is in the sequence.
    # usage: mhinseq seq 42

    mark -list -sequence "${1?}" |
    awk -v RS=' ' -F - -v msg="${2?}" '
            $0+0 &&
                ((NF == 1 && $1+0 == msg) ||
                 (NF == 2 && $1 <= msg && msg <= $2)) {f=1; last}
            END {exit !f}
        '
    $

Cheers, Ralph.
