perlfaq nodetype faq_monk D <P> The <CODE>&lt;&gt;</CODE> operator performs a globbing operation (see above). By default <CODE>glob()</CODE> forks <CODE>csh(1)</CODE> to do the actual glob expansion, but csh can't handle more than 127 items and so gives the error message <CODE>Argument list too long</CODE>. People who installed tcsh as csh won't have this problem, but their users may be surprised by it. <P> To get around this, either do the glob yourself with <CODE>Dirhandle</CODE>s and patterns, or use a module like Glob::KGlob, one that doesn't use the shell to do globbing. <P>
