[GRASS-user] Error in a script that calls g.mapset

[Helena Herrera]

hello

I'm sorry for bothering you but I have sent this question last week and I
didn't get any answer.

I have a Python Script (for GRASS6.4) where I run this:
grass.run_command("g.mapset", mapset = t_mapset)
(to change active mapset)
But I get all this in the command output:

temporary files... Your shell continues to use the history for the old
mapset You can switch the history by commands: history -w; history -r
/usr/local/share/grassdata/Place/National/.bash_history;
HISTFILE=/usr/local/share/grassdata/Place/National/.bash_history

It seems to be running ok without any impact but:
1- Why is this happening?
2- How can I avoid this?

Thanks
Helena
