( #3333=superdoc: print w/replies, xml ) Need Help??
I need to get a count of how many unique data values I have in my text file.
The text file has data like this:
123 56 123 56 234 45 123 56 678 93 678 93
I need the results of my script to look like this:
234 45 1 123 56 3 678 93 2
Here is my attempt and its not printing any data:
my $file = 'filehere.txt'; open(DATA, "$file") || die "Can not open: $!\n"; my @array = (<DATA>); close(DATA); open(DATA, "$file") || die "can t open: $!\n"; my %hash = (); foreach $item (@array) { $hash{$item}++; } print "$item\t$hash{$item}\n"; close(DATA);

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.
