Concessio – understand file permissions

Concessio is a graphical tool that’s designed to help you understand file permissions in Linux.

The Unix permission system is used to grant granulated access to files and directories. Permissions are granted to three groups: User (the owner of the file), Group (a group of users who share access to the file), and Others (all other users on the system).

The types of permission are: Read (view the file’s contents or listing a directory’s contents), Write (allows modifying the file’s contents or creating/deleting files within a directory), and Execute (allows running the file as a program).

Permissions can be represented symbolically or numerically. Symbolic permissions are represented as a string of 10 characters. Numeric permissions are represented by three numbers (octal notation).

This is free and open source software.

Features include:

• Convert between symbolic and numeric representations of UNIX file permissions.
• Use toggle buttons to update the symbolic and numeric fields.
• Open a file to read its permissions and convert them.
• Open the help dialog to read and understand the UNIX permissions system.
