Perhaps that data contains '<<<<<' in it already? Try print "--->>>>$line\<<<<---\n"; Just in case it's seeing it as a varaible named 'line<..' That could cause all sorts of screwy ness
For kicks what does it ouput if you do : print "\n---- start line ---- \n $line \n---- end line ---- \n"; Dan -----Original Message----- From: Jason Frisvold [mailto:[EMAIL PROTECTED]] Sent: Wednesday, January 08, 2003 1:39 PM To: Perl Beginners List Subject: "hidden" characters in an input stream Hi all, I'm using the Net::Telnet module to automate some of the more menial tasks I have to deal with every so often. Part of the task requires parsing a stream of data from the device I'm telnetting to (A Marconi ASX-200 to be exact) ... I've successfully set up the telnet, logged in, and executed the proper commands. Now, however, I need to retrieve data from the device. I can submit the command and use getline() to retrieve lines, one at a time, and parse it. However, there are "hidden" characters here and I don't know how to determine what they are. Here is a quick snippet of the code : $Telnet->print("sec log sho"); while (my $line = $Telnet->getline(Timeout => 5,)) { chomp $line; print "--->>>>$line<<<<---\n"; } This should simple print out each line with the arrows before and after the line. However, upon output, I get something like the following : --->>>> sec log sho<<<<--- UserName Application Authentication Method Profile Name<<<<--- --------------------- ----------- --------------------- --------------------<<<<--- myuser console password admin<<<<--- myuser http password admin<<<<--- myuser telnet password admin<<<<--- I'm guessing this is a carriage return character? I believe that's the one that causes the output to start at the beginning of the line. Does anyone know how I can properly remove these characters so I can parse this information? In addition, is using the timeout on getline the "proper" way to determine that the input stream has stopped? Thanks, -- --------------------------- Jason H.
