我怎样才能在 Perl 的路径中获得两个级别的目录?
How can I get the directory two levels up in a path in Perl?
如何从 perl 中的环境变量向上移动两个目录?
sub do_file_tracing {
my var = "$ENV{IMPORTANT_DIR}";
}
我想在 long/path/to/the/important_dir
long/path/to/the/important_dir/../../
处创建一个文件,即 long/path/to/
使用Path::Tiny。例如:
use Path::Tiny;
my $dir = path($ENV{IMPORTANT_DIR})->parent(2);
my $dir_qfn = "$ENV{IMPORTANT_DIR}/../..";
