Wrong. system() can take a single string or a list of strings (and an optional direct object). If a list of more that one string is given, then Perl won't call a shell to interpret the command-line string (that you didn't give it). If just one string, then Perl will call a shell if the string isn't simple enough (that is, if the string doesn't have any shell meta characters, it will just split it on whitespace and use fork()/exec() just as if you had given it more than one value).

Of course, platforms that don't have fork() don't quite obey this rule.

    tye, perlfunc system() doesn't talk about taking an optional direct object nor am I finding it in any of my books. Where would I go to find more information on this topic?

      In the following, the "PROGRAM" (which isn't followed by a comma) is the optional indirect object: 

          system LIST
    system PROGRAM LIST
[...]
            Like `exec', `system' allows you to lie to a program
            about its name if you use the `system PROGRAM LIST'
            syntax. Again, see the exec entry elsewhere in this
            document.

      at least I think that is what Larry called that.
