Try this sample code:
Code:
#!/bin/bash
su -l guest -c "export a=$1;export b=$2;echo \`whoami\`>/tmp/me;echo \$a >/tmp/a;echo \$b>/tmp/b"
echo Now I am
whoami
echo -----------
echo Contentes of file me
cat me
echo -----------
echo Contentes of file a
cat a
echo -----------
echo Contents of file b
cat b

And this is the output I am getting:
Code:
./test.sh 1 2
Now I am
root
-----------
Contentes of file me
guest
-----------
Contentes of file a
1
-----------
Contents of file b
