А за такой совет что ты отобьешь? (о:
=== Start of Windows Clipboard ===
use Cwd;
$dir = cwd(); # get current working directory safest way
$dir = getcwd(); # like getcwd(3) or getwd(3)
$dir = fastcwd(); # faster and more dangerous
use Cwd 'chdir'; # override chdir; keep PWD up to date
chdir "/tmp";
print $ENV{PWD}; # prints "/tmp"
cwd() gets the current working directory using the most natural and safest form
for the current architecture. For most systems it is identical to `pwd` (but
without the trailing line terminator).
getcwd() does the same thing by re-implementing getcwd(3) or getwd(3) in Perl.
fastcwd() looks the same as getcwd(), but runs faster. It's also more dangerous
because you might chdir out of a directory that you can't chdir back into.
It is recommended that one of these functions be used in all code to ensure
portability because the pwd program probably only exists on UNIX systems.
If you consistently override your chdir built-in function in all packages of
your program, then your PWD environment variable will automatically be kept up
to date. Otherwise, you shouldn't rely on it. (Which means you probably
shouldn't rely on it.)
=== End of Windows Clipboard ===
... bye.
