Do you know where your variables are?

The first comma was removed from each number.

The s/// operator by default removes only the first match. So:

my $var = "foobarfoobaz"; $var =~ s/foo//; say $var; # says "barfoobaz"

There are various flags you can include to alter its default behaviour though. One of the most useful is the "g" (global) flag...

my $var = "foobarfoobaz"; $var =~ s/foo//g; say $var; # says "barbaz"

Note that the slashes may be replaced with other characters, so you could equally write:

my $var = "foobarfoobaz"; $var =~ s@foo@@g; say $var; # says "barbaz"

Or even:

my $var = "foobarfoobaz"; $var =~ s{foo}{}g; say $var; # says "barbaz"

... which some people might find more readable. Though note that there are a handful of characters (hash, question mark and single quote spring to mind) that trigger special behaviours here (perlop has more details).

Use:  <p> text here (a paragraph) </p>

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.
