Select the permissions you require below. The tool will provide you with an octal code that corresponds to these permissions which can then be applied to relevant directories and files with chmod.
To understand file permissions, you first need to know what they do. So let's start by explaining what they're used for.
File permissions control how users access files on your computer and determine whether someone can read, write, execute, delete, or change a file.
A file permission is a set of rules determining who has access to a particular file. There are three main categories of file permissions: Read, Write, Execute.
If you're using Linux, macOS, or Windows, you'll probably need them at some point. They determine whether users can read, write, or execute files.
You can set permission levels for individual files or folders, and this lets you control who has access to each one.
To check file permissions, you must first determine whether you are looking at a folder or a file. If you are viewing a folder, you will see a list of the contents inside. If you are viewing an individual file, you will only see its name.
You can use the chmod command to set permissions on files and folders. This command allows you to specify how users can access and modify the file or folder. Three different ways to set permissions are read, write, and execute.
Symbolic notation is used to change the permissions of files and directories relative to their current permissions.
To use this tool set the current octal value of your file permissions and then select from the checkboxes below to create the target permissions for your file(s).
To change directory permissions in Linux, use the following:
Ooctal numbers specify the attributes for the files by ORing together these bits.
4000 Set-user-ID bit
2000 Set-group-ID bit
1000 Sticky bit
0400 User read
0200 User write
0100 User execute (or list directory)
0040 Group read
0020 Group write
0010 Group execute
0004 Other read
0002 Other write
0001 Other execute
