End of expect script syntax question

[RFC1795]

Hi All,

I have some hand me down expect scripts that I've been responsible for the past few years. They all have the following at the end of them:

for {} 1 {} {
expect eof {
exit
}
}

Anybody able to explain exactlly the purpose of this?

The expect scripts are usually called from a normal shell script in a for loop.

Thanks .. T
