Input to Expect Script

Question

in my test file, I had this line hello$LG. So, if I do

`cat /test`

It will show in my bash shell - hello$LG

But when I try to do this in my expect script,

$> expect test.sh `cat /test`

It gives me this {hello$LG} . I don't know why it is getting {}. Anyone knows how to fix this?
