I think the main thing going wrong is that your first argument needs to be a block of code rather than a scalar. grep works by running the block of code for each element in the array and returning the number of times it was true (or, if you did @output = grep... it gives you the list of elements from your input array for which it was true... but you don't care about that).

So this

if(grep($username =~ m/\b$_\b/, @ignore)) {
     print "That didn't quite work";
}

... may do what you want. (the \bs are so you only catch whole words).

• 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.
