Dear Jim
I use nohup (ubuntu linux), and I have a feature request.
Often I run more than one program at a time under nohup, and some of these programs run for at
least a couple of hours.
Every now and then nohup writes the output to nohup.out, which I find very
useful.
My request is: could

Hi,
would it be an option to use Genparse (http://genparse.sourceforge.net/)
for command line parsing in the GNU Coreutils?
I'm one of the developers of Genparse and I recently used some of the
well known Coreutils as an exercise for testing Genparse (see

I like the examples. But there are almost 100 programs in the
coreutils. If genparse can really handle all of those use cases
without causing any significant degradation in the tools, then
it will be hard to object.

That's not possible unfortunately, as nohup just
sets things up, and replaces itself with the command.
It might suffice to have separate files for each command,

Welcome to floating-point roundoff errors. The decimal constant 0.1
cannot be exactly represented as a floating-point number on modern
hardware, so
Micah Cowan scripsit:
You need to use something more like:
$ echo `seq 0.0 0.1 0.91`
0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9
Or better yet, use `seq 0 9` and prepend the 0. part yourself.

Of course it is possible; nohup knows its pid as well as the command it
is asked to run. When it opens the output file it just needs to use

That implies using either a fixed-point or a decimal-based floating-point
