Perl -b -c Keywords
The -C keyword
-C is a file test that returns the inode change time minus file modification time, in days (in Unix; may differ for other platforms)..
It takes one argument, either a FILENAME, a FILEHANDLE, or a DIRHANDLE to test the associated file to see, if something is true about it. If the argument is omitted, it tests $_. -C returns 1 for true and an empty string for false. If the file doesn't exist or can't be examined, it returns undef and sets $! (errno).
