I started using expect. I have a simple script. But I have a problem. I want to init a variable which has a $ an first character:

set mystring "$THIS_IS_MY_STRING%"

So I get an error, because expect expects a variable. How can I fix this?

回答1:

Escape any special characters such as the dollar sign by proceeding them with a backslash, so your code becomes

set mystring "\$THIS_IS_MY_STRING%"
