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.
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:
allows a user to list the contents of the AFS directory, examine the ACL associated with the directory and access subdirectories. Insert (i) allows a user to add new files or subdirectories to the directory. Delete (d) allows a user to remove files and subdirectories from the directory. Administer (a) allows a user to change the ACL for the ...
ext2 was the default filesystem in several Linux distributions, including Debian and Red Hat Linux, until supplanted by ext3, which is almost completely compatible with ext2 and is a journaling file system. ext2 is still the filesystem of choice for flash-based storage media (such as SD cards and USB flash drives) [citation needed] because its ...
The setuid permission set on a directory is ignored on most UNIX and Linux systems. [5] [citation needed] However FreeBSD can be configured to interpret setuid in a manner similar to setgid, in which case it forces all files and sub-directories created in a directory to be owned by that directory's owner - a simple form of inheritance.

Password-aware operating systems should not hide password-protected files from directory views, even if this bit may be set. The password protection mechanism does not depend on the hidden attribute being set up to including DR-DOS 7.03, but if the hidden attribute is set, it should not be cleared for any password-protected files. 2 0x04 System.
A directory can have at most 31998 subdirectories, because an inode can have at most 32,000 links (each direct subdirectory increases their parent folder inode link counter in the ".." reference). [16] On ext3, like for most current Linux filesystems, the system tool "fsck" should not be used while the filesystem is mounted for writing. [3]
A directory is a logical section of a file system used to hold files. Directories may also contain other directories. The cd command can be used to change into a subdirectory, move back into the parent directory, move all the way back to the root directory or move to any given directory.
