So it looks like the problem is with the regular expression matching, can anybody help me as to why and how to fix it?
Here is where it fails, it doesn't know it is in enable mode
expect: does "<switch>> (enable) " (spawn_id exp6) match regular expression "<switch>> \\(enable\\)"? no
"[\n\r]+"? no
expect: timed out
Error: TIMEOUT reached
write() failed to write anything - will sleep(1) and retry...

Post by john heasleyPost by Lance VermilionMina,
I am assuming with user interaction it works just fine versus running
the command as a passed in argument.
John,
Any idea why it would recognize the prompt enough to send set term
length 0 but not recognize it afterwards?
Maybe its running on freebsd? Or someone has altered the script? or
Sorry, to explain the freebsd comment; at one point they imported a
version of expect or patched it or whatever in/into frebssd-ports and
a few things were broken, globs among them and regexes were acting
funny.
