filetest - Perl pragma to control the filetest permission operators
This pragma tells the compiler to change the behaviour of the filetest permission operators, "-r" "-w" "-x" "-R" "-W" "-X" (see perlfunc). The default behaviour of file test operators is to use the simple mode bits as returned by the stat() family of...
