Yes, it is possible.

You can use whatever scripting language you like.
I'm not sure where there is a web page to help with this.

If you know the commands that you type to do something, type them into
a file using a text editor, and then use the . (dot) command to execute
the file.

Like this;

GRASS:~/gis > echo "d.mon start=x0" > start
GRASS:~/gis > echo "g.region -d" >> start
GRASS:~/gis > . start

I think it can also be done by tcltkgrass, but mine is no longer
starting, anyone have any ideas;  [thread hijack, change subject]

GRASS:~/gis/old > tcltkgrass
