I like the grep stuff.  If anyone's interested, I have a similar sort of
script which takes a slightly different approach, in that it runs the
target command as a child, passing arguments, much as nice(1) does.

Most critical reason for doing this is that I can actually be told when
a command fails -- mailwrap(1) reports non-zero exit codes, reports
aborts on signals and core-dumps.  I've seen too many commands which
produce no output when failing, but do leave an exit-code to indicate a
problem.

Optional fork/detach.  Much control of mail headers and SMTP Envelope
Sender.  Calls system mailer directly, feeding it a message.  Actually
codes for "exim", but that's simply because that's the MTA we use;
should work just fine with sendmail, since it's the Sendmail interface
used.  Is very paranoid about not allowing address insertion through
header manipulation.

mailwrap(1) available upon request.
