chmod 563

What does chmod 563 mean?

Chmod (change mode) is a UNIX/Linux command that you can use to change permissions on a file. Here we will explain how the chmod 563 UNIX/Linux command changes your file permissions. We start by color-coding the three digits in 563, like this, so it is easy to follow along:

The three digits refer to three different permissions:

5: Owner Permissions
6: Group Permissions
3: Everyone Permissions

Furthermore, chmod digits give the following kind of permissions:

1 = Execute
2 = Write
3 = Write & Execute
4 = Read
5 = Read & Execute
6 = Read & Write
7 = Read, Write & Execute

Now, when we put it all together, we can see what the chmod 563 command means and what it will do to your file permissions:

5: Owner can read and execute
6: Group can read and write
3: Everyone can write and execute
