Umask is a command in computers which provides the settings of a mask which controls the file permission for every filed that has been created. Umask can also be a function that puts the mask or only refers to the mask of the file. There are times when you are setting permissions for files in linux and all you have is the command line or the shell. This calculator was created for the linux system administrators to assist in assigning permissions to files and folder in a Linux operating system. We have developed a permissions calculator tool which helps you. You can enter the mask value to convert into regular file permissions. Also, we created a umask calculator. its very easy to use, all you have to do is enter the umask value and it converts it into the file permissions you want. There are cases when you may need to use this calculator, for example, when you are taking a test. One example is the Linux COMPTIA Linux Exam. You will need to know about umask if you wish you become certify, this calculator will help you understand.
