(The file test may also be a ``cd'', causing subsequent relative filenames to be interpreted relative to that directory.) After the file test you may put [perlfunc:die|die] to make it a fatal error if the file test fails. The default is [perlman:perlguts|perlguts]. The file test may optionally have a ``!' prepended to test for the opposite condition. If you do a cd and then list some relative filenames, you may want to indent them slightly for readability. If you supply your own <CODE>die()</CODE> or <CODE>warn()</CODE> message, you can use <CODE>$file</CODE> to interpolate the filename. <P> Filetests may be bunched: ``-rwx'' tests for all of <CODE>-r</CODE>, <CODE>-w</CODE>, and <CODE>-x</CODE>. Only the first failed test of the bunch will produce a warning. <P> The routine returns the number of warnings issued. <HR>
