SJ Chmod Calculator

SJ Chmod Calculator is a free application designed for system administrators, developers and Linux or Unix users who need to calculate, understand and convert file permissions quickly and without errors.
With its clear and intuitive interface, the app makes it easy to switch between numeric codes and symbolic notation. You can enter a three-digit chmod value such as 755, 644 or 600 and instantly see both the permissions table for user, group and others as well as the equivalent symbolic representation like rwxr-xr-x.
Alternatively, you can simply select the read, write and execute rights in an interactive table and the app will automatically calculate the numeric value and the symbolic Unix notation.
Fast, accurate and simple to use, this tool is perfect for developers, system administrators, students or advanced users who want to master Unix and Linux file permissions with confidence.
