Using MH from Other Languages

Programs that use MH commands don't have to be interpreted by the Bourne shell, of course. An MH command may be run by any language that will start a UNIX process and can:

So, instead of using MH format strings, a Perl script might use show -noshowproc or mhpath to read a message header into an array -- then use Perl regular expression operators to get the information you need.
