Frequently Asked Questions

What is chmod 777 or 700?

In the chmod command, the numeric values 777 and 700 represent different sets of permissions for a file or directory. In chmod 777, The user gets read (4), write (2), and execute (1) permissions, which sum up to 7. The group also gets read, write, and execute permissions (7). Others (users who are neither the owner nor in the group) get read, write, and execute permissions (7). On the other hand, in chmos 700, the user gets read (4), write (2), and execute (1) permissions, which sum up to 7. The group and others get no permissions (0).

What is 5 in chmod?

In the chmod command, the numeric value 5 typically represents a combination of read (4) and execute (1) permissions. When you see the numeric value 5 in the context of file permissions, it often means: Read permission (4) is included, as it is the most significant digit. Execute permission (1) is included, as it is the least significant digit. So, the numeric value 5 corresponds to read and execute permissions. This might be used in the context of setting permissions for a specific entity (owner, group, or others) on a file or directory.

What is a chmod in Linux?

In Linux and other Unix-like operating systems, chmod is a command-line utility that is used to change the permissions of a file or directory. The name "chmod" stands for "change mode," and it allows users to control who can read, write, or execute a file.

What is the use of chmod 755?

The chmod 755 provides the owner with full permissions (read, write, and execute), allows the group and others to read and execute the file, but does not grant them write permissions. This setting is commonly used for executable files, scripts, or directories where the owner needs full control, while others are allowed to read and execute.

What is chmod 600?

chmod 600 provides the owner with full read and write permissions, while the group and others have no permissions. This setting is commonly used for sensitive files that should only be accessible and modifiable by the owner.
