About chmod permissions:
- In Unix-like operating systems, the chmod (change mode) command is used to change the access permissions of files or directories.
- Permissions are divided into three user types, each with three types of permissions:(1). User: The owner of the file.(2). Group: The user group to which the file owner belongs.(3). Others: Users who are neither the file owner nor in the file owner's group.
- Each type of permission is as follows:(1). Read: Used to read file contents.(2). Write: Used to modify or allow modification of file contents.(3). Execute: For files, means the file is executable; for directories, means the directory can be traversed (i.e., entered).
- Permissions can be represented in octal or symbolic form:(1). Octal notation uses three octal digits, each representing a group of user permissions.(2). Symbolic notation uses character symbols to represent permissions.
