It may be useful to restrict the scope of the file handle as well, since slurping is a one pass approach. That may be done with

my $string = do { local $/; open local(*FILEHANDLE), 'somefile.txt' or die $!; <FILEHANDLE> };
or, better if lexical filehandles are available,
my $string = do { local $/; open my $fh, 'somefile.txt' or die $!; <$fh> };
since the lexical handle is properly closed when it goes out of scope. Either way ensures no interference with other handles of the same name.

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.
