Sorry to all Technical person for mistake of Question. Now i am post currect question Why copied file permission is changed in destination. When i give all permission i.e 777 to file and copy that to other location in destination the permission is 755. But if give permission 555 in destination that file permission is 555 and if give permission 444 to file after copy in destination the file permission is 444. These all are happening in normal user. How the umask value is calculate here really i am not understand. Please write the proper answer. Thanks in Advance
