perl脚本之目录

　　1）
　　The following get the script's directory, which is not the same as the current directory. It's not clear which one you want.

use Cwd qw( abs_path );
useFile::Basename qw( dirname );
say dirname(abs_path($0));
　　or

usePath::Class qw( file );
say file($0)->absolute->dir;
　　or

useCwd qw( abs_path );
use Path::Class qw( file );
say file(abs_path($0))->dir;
　　The middle one handles symlinks different than the other two, I believe.
　　
　　2）
　　To get the current working directory (pwd on many systems), you could use cwd() instead of abs_path:

useCwd qw();
my $path =Cwd::cwd();
print "$path\n";
　　Or abs_path without an argument:

useCwd qw();
my $path =Cwd::abs_path();
print "$path\n";
　　See the Cwd docs for details.
　　To get the directory your perl file is in from outside of the directory:

useFile::Basename qw();
my($name, $path, $suffix)=File::Basename::fileparse($0);
print "$path\n";
　　See the File::Basename docs for more details.
　　
　　3）
　　You could use FindBin:

use FindBin '$RealBin';
print "$RealBin\n";
　　FindBin is a standard module that is installed when you install Perl. To get a list of the standard pragmatics and modules, see perldoc perlmodlib.
