quotemeta EXPR quotemeta Returns the value of EXPR with all the ASCII non-"word" characters backslashed. (That is, all ASCII characters not matching /[A-Za-z_0-9]/ will be preceded by a backslash in the returned string, regardless of any locale settings.) This is the internal function implementing the \Q escape in double-quoted strings. (See below for the behavior on non-ASCII code points.) If EXPR is omitted, uses $_ . quotemeta (and \Q ... \E ) are useful when interpolating strings into regul

Instead, use ExtUtils::MM and it will figure out which MM_* class to use for you. DESCRIPTION See ExtUtils::MM_Unix for a documentation of the methods provided there.

On input, it converts the bytes expected to be in the specified character set and encoding to Perl string data (Unicode and Perl's internal Unicode encod

rmdir FILENAME rmdir Deletes the directory specified by FILENAME if that directory is empty. If it succeeds it returns true; otherwise it returns false and sets $! (errno). If FILENAME is omitted, uses $_ . To remove a directory tree recursively (rm -rf on Unix) look at the rmtree function of the File::Path module.
