Choose the permissions as used by the chmod command by clicking the checkboxes below.
Chmod is a Unix and Linux command which let the user change the access permissions for files and directories.
Our calculator has three mandatory columns: Owner, Group and Others, with three modes: Read, Write and Execute, and one column, Superuser, which is optional and specifies the special setuid, setgid, and sticky flags.
Chmod has two modes for usage: symbolic and absolute modes.
In symbolic mode you can add, delete or set specific modes while leaving the other modes untouched by using operators and letters.
In absolute mode you override the existing permission with a new value which is a three digits number (or four as the first digit is optional).
Use this calculator if you intend to use the absolute mode.
