simple script

I must be a retard since I can't even get this easy script to work:

With perl, I need to open the file "/etc/httpd/zipzap".  There will be two words in "zipzap" file that I need to save as variables.  The zipzap file has the format:

----------(beginning of file)
word1
word2
----------(end of file)

I need to then print them to the shell. (I will be doing other things with them which I already know how to do, I just want to print them to the shell to make sure the script is working.)

I want all the path information and everything else to be in the perl file.  I don't want to have to designate the path and filename of "zipzap" at the shell.  Thanks!  (feeling stupid)

 #!/bin/perl
  my $fname = "/etc/httpd/zipzap";
  open( TTT, $fname ) || die "Could not open file $fname - $!";
  @item = <TTT>;
  close TTT;
  print $item[0];
  print $item[1];

However, you might need the values without the inherent linefeeds so you need to add something like:

  chomp $item[0];

If i wanted to print them to a webpage, would this work?

print "Content-type: text/html\n\n";
print "<HTML><body>";
print "$item[0], $item[1]";
print "</body></html>";

Thanks again  :o)

Seems right, but I would use as few print statements as I could.  Saves execution  time.

  print "Content-type: text/html\n\n<HTML><body>\n$item[0], $item[1]\n</body></html>\n";

or

  print "Content-type: text/html\n\n"
    . "<HTML><body>\n"
    . "$item[0], $item[1]\n"
    . "</body></html>\n";

One last question, could you slightly modify the script for the case that the file "zipzap" has the format of:

word1:word2

This way I can see the pattern in how to read individual variables from a text file.  Thank you much and the points are yours upon your reply  :o)

Thanks again,

Tim
