In the command you have to put

sh /patch/to/script.sh

or if it needs root:

echo "sh /patch/to/script.sh" | sudo gainroot

And the script must contain the 2 commands in 2 different lines...
To do this you can use an editor (pygtkeditor) or do this through the terminal with the said commands:

echo comm1 > /patch/to/script.sh

echo comm2 >> /patch/to/script.sh
