touches on similar issues.

I post because I thought it might be generally useful to the populace
here.

Well, it seems that bash doesn't have some of the stuff ISTR from the
original *IX stuff (builtin alarm? not sure anymore). Anyway, a google
for "bash alarm trap" led to this and there are lots more. This was just
the first and may not be the best for your needs.

Anyway, sans "alarm", a trap, sleep, SIGUSR* or SIGINT combination should
do nicely.

Do "man bash" and search for "trap". For those not familiar, it can be a
little confusing, but it's well worth the effort, in terms of results
and learning.

Helped by circumstances. _Normally_, the default install has those
aliases only assigned for root, due to the great risk to the system.

So it would be a natural assumption. As usual "assume" has its risks.

Well, I think its utility is such that it ought to be in the wiki hints.
If you have time and interest, why don't you ask the folks for access
and location in the wiki? Adding a little commentary about the meaning
of the values would make it useful to similar, but slightly different,
setups as well.

Glad you "fingered" it out.
