Hi, If you want to chain multiple s/// statements, then you can use a comma and get rid of the ugly do and the curlys.
foreach my $entry ( split( /;/, $file_data ) ) { s/^\s+//, s/\s+$// for $entry; push @email_list, $entry; } print join( "\n", sort(@email_list)), "\n";
If you are a Perl::Critic follower then you are not allowed to use the for statement modifier Perl::Critic::Policy::ControlStructures::ProhibitPostfixControls. However consider this using List::MoreUtils apply function.
use List::MoreUtils qw(apply); foreach my $entry ( split( /;/, $file_data ) ) { push @email_list, apply { s/^\s+//; s/\s+$// } $entry; } print join( "\n", sort(@email_list)), "\n";

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 or How to display code and escape characters are good places to start.
