The wisdom of Cave Johnson
There's been a similar Futurama thing around for a while, which grabs a quote from the /. headers [curl -Ism3 slashdot.org | egrep "^X-(F|B|L)" | cut -d \- -f 2- | fmt -w $(tput cols)]. Same deal, but more likely to stop working when someone forgets to pay the bill on the domain. Until then: Cave Johnson!

sends commands specified in $commandfile to the telnet-server specified by $telnetserver. to have newlines in $commandfile interpreted as ENTER, save the file in CR+LF (aka "Windows-Textfile") format. if you want to save the output in a separate file, use: $nc $telnetserver 23 < $commandfile > $resultfile
