Possible; just append "gis.m &" to the temporary .bashrc file which it
creates.

You can't "source" a bash script from Tcl, and "exec"ing it won't
affect gis.m's environment.

That will only work for .grass.bashrc, not for .grass.cshrc (init.sh
is a Bourne-shell script, so it can't "source" a csh script).

I'd suggest having a distinct "config" script for GRASS, which
contains Bourne-shell commands (mainly environment settings) and which
is sourced at the beginning of Init.sh.

~/.grass.bashrc (and cshrc) are meant for the session shell; nothing
in them can affect Init.sh itself.
