( #3333=superdoc: print w/replies, xml ) Need Help??
Hi, I have 2 files (both which are rather large) but with the same number of lines. What I would like to do is read the the first line from the first file, and then the first line from the second file, and compare the contents of the two lines. But all my previous experience with filehandles in perl, I have while loops that read one file at a time. I can't seem to work around this. Can you guys point me in the right direction? Thanks for your help. ****** wait I think I got it:
#!/usr/bin/perl -w + + + use Data::Dumper; open(FILE1, $ARGV[0]); open(FILE2, $ARGV[1]); while ($line = <FILE1>) { my $line2= <FILE2>; chomp($line); chomp($line2); print "$line $line2\n"; }

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
