Summary

0000026: poor man's "scriptable" telnet

Description

with most telnet programs you can do something like this:

    (
     sleep 2
     echo username
     sleep 2
     echo somepassword
     sleep 2
     echo date
     sleep 2
    ) | telnet somehost > session.log

there's no error checking, and no synchronization. but for a quick and dirty solution it can be handy.

this doesn't work in busybox because busybox telnet exits if stdio is not a terminal. the following patch (only quickly tested) makes this work.

Additional Information

it's clear that there are better tools for this job -- both expect and nc are probably more suited. but expect is probably too big for an embedded system, and nc isn't always configured. and this is a pretty cheap fix.
