will first remove baz/, then bar/ and finally foo/ thus removing the entire directory tree specified in the command argument. rmdir will not remove a directory if it is not empty in UNIX. The rm command will remove a directory and all its contents recursively. For example:
rm (short for remove) is a basic command on Unix and Unix-like operating systems used to remove objects such as computer files, directories and symbolic links from file systems and also special files such as device nodes, pipes and sockets, similar to the del command in MS-DOS, OS/2, and Microsoft Windows.
Remove a directory (delete a directory); by default the directories must be empty of files for the command to succeed. The command is available in MS-DOS versions 2 and later. [1] The deltree command in some versions of MS-DOS and all versions of Windows 9x removes non-empty directories.
In MS-DOS, PC DOS and Windows 9x, DELTREE was implemented as an external command, with its functionality kept in a separate file outside of COMMAND.COM. [7] Normal operation prompted the user for verification that the specified directories were indeed intended to be removed, but this safeguard could be suppressed with a command-line option. [5]
When a directory's sticky bit is set, the filesystem treats the files in such directories in a special way so only the file's owner, the directory's owner, or root can rename or delete the file. Without the sticky bit set, any user with write and execute permissions for the directory can rename or delete contained files, regardless of the file ...
Worse, if recursively deleting, such programs may attempt to delete a parent of the directory it is currently traversing. Note that both of the conditions listed above exist in the system of hard links established on the C: drive in the default Windows setup. For example, every Windows 10 installation defines the recursive path:
Red Hat Enterprise Linux (RHEL) is a commercial open-source [6] [7] [8] Linux distribution [9] [10] developed by Red Hat for the commercial market. Red Hat Enterprise Linux is released in server versions for x86-64 , Power ISA , ARM64 , and IBM Z and a desktop version for x86-64.
The magic SysRq key is a key combination understood by the Linux kernel, which allows the user to perform various low-level commands regardless of the system's state. It is often used to recover from freezes , or to reboot a computer without corrupting the filesystem . [ 1 ]
