chmod 671

What does chmod 671 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 671 UNIX/Linux command changes your file permissions. We start by color-coding the three digits in 671, like this, so it is easy to follow along:

671

The three digits refer to three different permissions:

6: Owner Permissions
7: Group Permissions
1: 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 671 command means and what it will do to your file permissions:

6: Owner can read and write
7: Group can read, write and execute
1: Everyone can execute

chmod 670
Here is the next chmod command on our list that we have explained for our fellow UNIX/Linux fans.
