Lets say file 1 is: foo bar ... continues on for 100 lines And file 2 is: foo baz bar ... continues on exactly the same 100 lines as file 1 Would file 2 be different from file 1 from line 2 and down? Or would it be different for line 2 and 3? Also, the keywords: next; Brings you to the next

How do I set up bidirectional pipes over a network connection?

I have 2 Linux boxes I want to talk to each other over the local network using a Perl script. Is it possible to set up a bidirectional pipe so that 2 perl daemons can communicate with each other? How would I go about doing this and are there any modules to help? Thanks in advance, Dan -- To

What are the dangers of leaving a cgi-bin directory CHMOD 777

I have a perl script that writes to its directory, and as such the directory is CHMOD 777 in my cgi-bin. (Linux box) I figured this might be dangerous, but didn't think there was any harm in it. Am I right or will the script kiddies be all over me? -Dan -- To unsubscribe, e-mail:

Replacing text

I have a script that reads text from a file and inserts text into different places depending on what it needs to do. But I use split to replace the text, i.e.: ($first_part, $second_part) = split "#INSERT#TEXT#HERE#", $document, 2; print FILEHANDLE $firstpart, $text_to_insert, $sec

Re: Viewing logs on other computers.

Although it's not quite the same thing, I wrote a pretty simple Perl script to keep track of disk space usage on a number of file servers. Because df needed to be run as root (access to /proc wasnm't allowed for underprivileged users) I setuided it to root. If I were

How does perl compile functions

I'm curious how perl "compiles" functions internally. When the actual C code (or ASM equivalent or bytecode or whatever Perl uses) for a function is run, is there overhead to the function? Are functions inlined? Does perl lazy compile functions? (i.e. functions never used are never compiled and

Is it possible to create a perl script that would send to the user an image and cookies. Depending on the cookie on the users computer, the user would get a certain picture. I figure I would have to use CGI, but what else, if anything, would I need to do? Thanks in advance, -Dan -- To unsub

In case anyone is wondering why I want to do this, I am running through an array (popping out all elements) in order. Some things from the array act differently depending on what is left or right of them (if I'm shifting or popping respectively). I want to double check before I pop or shift. -Da
