Well, let me help you there...

"foo" is just a term to specify something... When you hang around longer you'll see a lot of Monks using foo for a variable name like $foo = "bar"
"bar" is like foo.(eg: $bar = "foo")
"grep" is a function in perl which will enable you to easily search through lists (and much more once you get the hang of it)
"carp" and "croak" are also functions in perl, which make perl die (aaaah....)

So now you know!

• 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.
