As
Zaxo said, there seems to be a confussion on
$ENV{PATH} and
$ENV{PWD}. The full path solution will work for gzip, but in the interest of over-answering questions so we all better understand Perl, I would also like to add a comment on actually changing directory in Perl :
Getting Current Directory: You can use the
Cwd module to get a portable way of getting the current directory. It works like this :
use Cwd;
$dir1 = cwd();
$dir2 = getcwd(); # C version of cwd()
$dir3 = fastcwd(); # less stable , faster C version
Setting Current Directory: Setting the current directory is not usually needed as complete paths would be prefered. In the event that a program being started does need a specific current directory, or if
chroot is being used, it can be done as follows :
my $dir = '/tmp';
chdir($dir) || die "Failed to cd : $!\n";
Hope that helps soemone.
OH, a sarcasm detector, that’s
really useful
