When you need to make a call for system resources try to see (or search in portuguese) if similar command are available on builtin funtions...

$ perldoc -f readlink readlink EXPR readlink Returns the value of a symbolic link, if symbolic links are implemented. If not, gives a fatal error. If there is some system error, returns the undefined value and sets $! (errno). If EXPR is omitted, uses $_.

This resource is new for me, but my first try is perldoc local or via web. (the second is CPAN! ;)
