Those who have used a Unix-based operating system are probably familiar with the term Chmod 777. However, you may not know exactly what it means and how to use it. There is no reason to worry, here we will take a closer look at this term to help you clarify things. Let’s start by saying that Chmod is the command and system call in Unix based OS, which is used to change the access permission to file and directories. If you attempt to edit a file or upload data into a directory, you may see an error stating that there is no permission for the file. Let’s take a closer look at Chmod 777 and its meaning in Unix.

What is Chmod 777?

It is important to note that in Unix based OS, there are two main aspects to note for files and their permissions. The first is the class of users that are able to access the file and the second is the kind of permissions available for each class of users. There are three different classes of users to note: Owners, Groups and Others. As the name suggests, Owners are the users who own the files and can edit them. Groups refers to group of users and like the owners, they have permissions to edit files. “Others” refer to general users who have limited access.

When it comes to permissions, there are three types to keep in mind: Read, Write and Execute. Read mode only provides permission to read the content of the file. In order to be able to edit a file, you need Write permission. To run the script of the file, you will need execute permissions. The access to a file is determined by the classes and permissions. Read is the same as 4-bit data and as such it is usually refereed to as 4. Since Write command is 2-bit data, it is mentioned as 2, while Execute is 1 bit. It should be noted that there are different combinations of Read, Write and Execute.

Different combinations:

0 – No permission
1 – Execute
2 – Write
3 – Write and execute
4 – Read
5 – Read and execute
6 – Read and Write
7 – Read, write and execute

The number 7 in Chmod involves read, write and execute permission, but to understand why there are three 7’s in Chmod, we need to keep in mind the classes of users. We mentioned before that we have: Owners, Groups and Others. The three 7’s in Chmod refer to these three classes of users. The first 7 refers to Owners, the second to Groups and the third to Others. In essence, chmod 777 indicates that owners, groups and others have permissions to read, write and execute files. Below, you will see some combinations and what they mean.

Chmod 777 – Read, write and execute for owners, groups and others
Chmod 755 – Read, write and execute for owners, read and execute for groups and others
Chmod 655 – Read and write for owners, read and execute for groups and others

There are also combinations based on your requirement for the file and directory.

Using Chmod 777

CHMOD 777 [FILE LOCATION AND NAME]

As an alternative, it is possible to select the file and then click properties and choose the permission for the file or directory.

Every bit set in the umask for the process “masks”, or “takes away”, that permission from the default permissions for newly created file system objects created by that process. 5 lions pragmatic play. The umask value is a mask; it turns off permissions so that they are not assigned to newly created objects.

“Mask” does not mean “subtract”, in the arithmetic sense – there is no borrow or carry involved. The two binary bits 10 masked by the two bits 01 result in the two bits 10. (The mask 01 turns off the rightmost bit; but, it was already off, so no change.) The two bits 10 masked by the two bits 11 result in the two bits 00. (The mask 11 turns off both bits.)

The umask is a mask; it is not a number to be subtracted. It turns off permissions that would normally be granted. Masking is not the same as subtracting, e.g. 666 masked with 001 is still 666 and 666 masked with 003 is 664. The mask turns off permission bits so that they are not assigned to newly created objects. If they are already off, the umask makes no change:
