Extra newline characters.
I'm working the exercises out of the Learning Perl book, but I'm doing so through a shell account from a Window$ box into a UNIX environment. I'm experiencing an oddity wherein I'm getting, what I think are, extra newlines or carriage returns in my code as I type it in the shell through a telnet session. This phenomenon, of course, throws off the results of the code. Has anyone experienced this? Is there a solution? I've tried several adjustments in the code I'm writing by using an extra 'chomp' or' chop', but this method is hit-and-miss. There may be some ENV variable or something else I can use to get some consistency going. TIA Ron - Do you Yahoo!? vote.yahoo.com - Register online to vote today!

Re: Extra newline characters.
I'm not sure what you mean. I'm new at logging into shell accounts through a 'telnet' session. I'm on a Window$ 2000 box, using 'telnet' to log into 'sdf.lonestar.org'. The first thing that appears at login is the following: NetBSD/alpha (sdf) (ttypu) Does that help?

RE: Extra newline characters.
Try: $ stty sane $ TERM=vt100; export TERM That will give you a common default terminal emulation. I would recommend getting a better windows client terminal. Some good free ones are putty and teraterm. Cygwin is a complete linux emulation package the runs on windows and includes decent terminal emulators (and I believe perl comes with it). -- This email is confidential and may be legally privileged.

Re: Extra newline characters.
Whoa! Easy big fella! sdf.lonestar.org is a *FREE* public access system. No reason for secrecy or alarm. Notice the *FREE* and remember, you get what you pay for. And they do tell you about using ssh for access when you initially sign up.

Yes, that helps, it tells us what OS you're writing for, and also how you connect to that OS (DOS telnet). Now, where do you develop your scripts? Do you write your scripts on the Win2000 machine and then copy/ftp them over to the UNIX box to test/implement? The more details you give us the better able we'll be to help! --Errin -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/ http://learn.perl.org/first-response

I'm wondering what shell you are using? you can type: # echo $SHELL on most UNIX accounts, this will be set for you and will contain your default shell. Kevin's suggestions will work with most shells, but Cshell would likely complain. I think your problem is more shell and terminal-emulation related, rather than Perl related. I'd suggest a good new-to-UNIX book, If I were you. Do you have a SysAdmin you can contact with problems or help-needed questions? If so, I would explain your problem to her/him as she/he (wow, that's annoying, huh? trying to keep PC is a pain!) would be most familiar with your environment and terminal options. I also agree with Kevin that a good terminal emulation program could help you. To follow Chris' advice, the really good ones will support SSH, as well.

Extra newline characters.
Thanks all. The problem was at the begining of the 'TELNET' session, I have to type in: UNSET CRLF. - Do you Yahoo!? Yahoo! Mail Address AutoComplete - You start. We finish.
