Hi,
since backticks are somewhat complicated to manage on some systems and
since the wxGUI command line actually "eats" them, it would be good to
have the possibility to output the result of g.mlist into an ASCII
file.
E.g. r.series accepts map lists from a file, so in a two-pass also
Windows users could easily process map series.
g.mlist rast pattern="precip*1951_1980_monthly_sums*" output=maplist.txt
r.series file=maplist.txt output=precip_0_25deg.1951.1980.sum method=sum
Makes sense?

It is a very good idea.
What about the standard output redirection (>)? g.mlist … > file.txt… Hmm… We can overwrite existing files…
-p and -f flags redirect outputs to a pager, so it won’t make sense for them to output to a file. Why don’t we make output=file and -p/-f mutually exclusive? See the attached patch.

This does not work from GUI and in terminal, it requires additional
knowledge. I'm not sure how if this works on MS Windows but even some Linux
now don't know this.

It doesn't, we tried. Perhaps under some conditions but not known to me.
but even some Linux now don't know this.

So it would be great and clear (and perhaps even "natural" given the
nature of a list generator) to have such an output.

Makes sense. If no objections, I’ll apply the two patches in this discussion.
BTW, does r.series take input from stdin? In terminal, g.mlist ¦ r.series would be great.

It doesn't understand "file=-" as referring to stdin (although that
would be a simple change), but on Unix you can typically use e.g.
"g.mlist | r.series file=/dev/stdin".

For consistency with other commands that would be a good change in r.series.
