grep { /^Julia_Roberts/ } @arr
should be enough. There's nothing particularly different with this "grep with multiple choice". The only thing it seems you are missing is that the grep block can match different values provided you code a suitable matching sub, like I did with a regex. If your problem is really to find out the array elements starting with $s, this will work:
grep { /^\Q$s\E/ } @arr; # regex with quoted interpolation # or grep { index $_, $s == 0 } @arr; # more efficient

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.
