expect

问题 I need to gather some statistics from a network switch and would like to use an expect script to output the data to a file.

"lookup string..." For expect -ex and expect -gl it is pretty easy to

问题 I'm new to expect scripts, so please forgive my stumbling... Below is the meat of my expect script. The intent is to scroll thru several screens of output, after each of which the user is prompted with "Continue? [y/n]". Finally, when there are no more screens, a "% " prompt is displayed, which SHOULD cause execution to fall out of the while loop. set more_screens 1 while {$more_screens > 0} { sleep 10 expect { "\[y/n]" { send "y\r"} "% " { set more_screens 0 } } } What happens instead is...
