( [id://3333]=superdoc: print w/replies, xml ) Need Help??

As Laurent_R said, your requirements have another dimension (or two), so my script won't work for this except for some of the basic ideas. You're probably going to want three hashes, one to collect per-hour values (%h) and one to collect per-minute value (%m), and one to collect database names (%db). Then you'll need to:

for each line parse out the date-hour, date-hour-minute, database name, and speed add speed to $h{date-hour}{database name} add speed to $m{date-hour-minute}{database name} $db{database name} = 1 # put database name in hash loop through sorted keys of %db print them as headers, formatted to fit what's coming below loop through keys of %h (sorted if you want) print the key (the date-hour) loop through sorted keys of %db print $h{$key}{database name} print a newline now do the same with the per-minute hash %m

Try coding that, and let us know if you need help.

Title:
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.
