Isso é fácil, siga o exemplo:
#!/bin/bash
echo "
##############################################
#
# to do somethings in two different terminals
#
##############################################
"
gnome-terminal -e "bash -c \"\
gedit; \
libreoffice; \
\ # You can put your script there, before the slash.
\
exec bash\""
gnome-terminal -e "bash -c \"firefox; cheese; exec bash\"" # Or just make it all in one line
exit 0
