In a Linux file system, each file or directory has a set of permissions that control who can read, write, and execute operations on it. Permissions consist of three different roles: owner, group and other users. Each role can be granted one or a combination of the following permissions:

• Read permissions (Read): Allows users to read the contents of files, view the list of files in the directory, and Get the attribute information of the file/directory.

• Write permission (Write): Allows users to modify file content, create or delete files, and create, rename, or delete files in the directory.

• Execution permission (Execute): For a file, execution permission indicates whether the file can be run as an executable file. For directories, execute permission allows the user to cd into the directory and access its contents.

Linux permissions are represented by three characters: r (read permission), w (write permission) and x (execute permission). These characters are often combined to form a string of nine letters or characters. The first three characters represent the owner's permissions, the next three characters represent the group's permissions, and the last three characters represent the permissions of other users.

So, "linux 501" can be read as:

• Owner has read and execute permissions (5 = r-x)

• The group to which it belongs has execution permission (0 = ---)

• Other users have read permission (1 = --x)

Please note that this is just one of the expressions of permission strings. Permissions can be expressed in different ways, such as octal (e.g. 755) or symbolic form (e.g. -rwxr-xr-x).
