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

But I wanted to mention my first impression when I saw that code in jmcnamara's node: "Oh, that takes way too much memory and will fail for files that don't fit within your available swap space".

I hope you realise that I was aware of that. :-)

This snippet's only real value is as a mild curiosity. When I first posted it here I wrote: "There are many ways of doing this and most of them are better".

If I really wanted a line count I would use one of the following in this order of preference:

wc -l file awk 'END{print NR}' file perl -nle 'END{print $.}' file

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.
