আমি এই জন্য ব্যাচ স্ক্রিপ্ট একটি সেট লিখেছেন। addpath.bat পাথের উপাদান যোগ করে, rmpath.bat পাথ থেকে উপাদানগুলি সরান, এবং lpath.bat শুধু পাথ তালিকাবদ্ধ করে। কিন্তু তারপর আমি কিছু সমর্থন স্ক্রিপ্ট প্রয়োজন, তাই chkpath.bat আছে।
এটি তুচ্ছ না এবং tr.exe এবং cat.exe, ইউনিক্স-স্টাইল ইউটিলিটিগুলির কয়েকটি প্রয়োজন। কারণটি তুচ্ছ নয়: cmd.exe এ কোন ব্যাকটিক্স নেই (যদিও আপনি এটির জন্য loops ব্যবহার করতে পারেন), এবং ছোট নামগুলি বনাম ছোট নামগুলি।

chkpath.bat
checks path for existence of the given segment.
Returns 1 if present, 2 if not present, 0 if not checked.
The matching and checking complicated by case sensitivity and "short pathnames".
created sometime in 2003 and lovingly maintained since then.
