[GRASS-user] Another script question

I know this is not strictly on-topic, but:

If I'm running a large bash script, how do I get it to write errors in Grass-GIS processes to a logfile?

That way, if I run a script overnight and a Grass-GIS process fails, I at least know there's a problem!

If either of the files $HOME/GIS_ERROR_LOG or $GIS_ERROR_LOG exist,
errors and warnings (but not messages) from GRASS commands will be
written to that file.

Or you can just capture all output from any command (including a
script) by appending "&>logfile" to the command.
