#3963 new enhancement

Document turning off progress messages on batch jobs

Description

On https://grass.osgeo.org/grass79/manuals/grass7.html , regarding running batch jobs, it needs to be mentioned how to suppress these six verbose lines, 

$ grass --exec true 2>&1 | nl
     1	Starting GRASS GIS...
     2	Cleaning up temporary files...
     3	Executing <true> ...
     4	Execution of <true> finished.
     5	Cleaning up default sqlite database ...
     6	Cleaning up temporary files...

in order to have a clean running batch job, (e.g., one that could be run by cron without sending the user an email message due to errors.)

Alas, the grass man page does not list a --quiet option.

Sure, the man page could simply say to use 2>&- or 2>/dev/null, but that would also wipe out real error messages.

Yes, a --quiet flag would be great for the grass7x start script.
