The chmod command is also capable of changing the additional permissions or special modes of a file or directory. The symbolic modes use ' s ' to represent the setuid and setgid modes, and ' t ' to represent the sticky mode.
Changes file ownership chmod: Changes the permissions of a file or directory cp: Copies a file or directory dd: Copies and converts a file df: Shows disk free space on file systems dir: Is exactly like "ls -C -b". (Files are by default listed in columns and sorted vertically.) dircolors: Set up color for ls: install: Copies files and set ...
Any user may create a sticky directory. See chmod(1) for details about modifying file modes. Historically, an executable shareable file which had the sticky bit set was not immediately discarded from swap space after execution. The kernel hoarded the text segment of the file for future reuse, thus avoiding having to reload the program.
The Unix and Linux access rights flags setuid and setgid (short for set user identity and set group identity) [1] allow users to run an executable with the file system permissions of the executable's owner or group respectively and to change behaviour in directories. They are often used to allow users on a computer system to run programs with ...
The read permission grants the ability to read a file. When set for a directory, this permission grants the ability to read the names of files in the directory, but not to find out any further information about them such as contents, file type, size, ownership, permissions. The write permission grants the ability to modify a file. When set for ...
Also, if a source file's timestamp is in the future, make repeatedly triggers unnecessary actions, causing longer build time. When Make starts, it uses the makefile specified on the command-line or if not specified, then uses the one found by via specific search rules. Generally, Make defaults to using the file in the working directory named ...

The most common special file is the directory. The layout of a directory file is defined by the filesystem used. As several filesystems are available under Unix, both native and non-native, there is no one directory file layout. A directory is marked with a d as the first letter in the mode field in the output of ls -dl [5] or stat, e.g.
