where name_of_directory is the name of the directory one wants to create. When typed as above (i.e. normal usage), the new directory would be created within the current directory. On Unix and Windows (with Command extensions enabled, [15] the default [16]), multiple directories can be specified, and mkdir will try to create all of them.
A related ambiguity arises when a filename is moved to an existing directory. By default, mv would handle this as one trying to move a name inside this directory. GNU mv has a -T switch for disabling this assumption and try to overwrite the directory instead. An inverse -t makes the move-to-directory operation explicit. [4]
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 attributes ln: Creates a link to a file ls: Lists the files in a directory mkdir ...
The default behavior of the mv and cp commands is to clobber their destination file if it already exists. This behavior may be overridden by invoking or aliasing the commands with the -i switch, causing the commands to prompt the user before overwriting the destination file, or -n to not transfer source files with a naming conflict.
A directory whose "sticky bit" is set becomes a directory in which the deletion of files is restricted. A file in a sticky directory may only be removed or renamed by a user if the user has write permission for the directory and the user is the owner of the file, the owner of the directory, or the super-user.
For example, Windows Vista users must manually indicate when creating a symbolic link whether it is a file or a directory. [17] Windows 7 and Vista support a maximum of 31 reparse points (and therefore symbolic links) for a given path (i.e. any given path can have at most 31 indirections before Windows gives up). [18]
In computing, tar is a computer software utility for collecting many files into one archive file, often referred to as a tarball, for distribution or backup purposes. The name is derived from "tape archive", as it was originally developed to write data to sequential I/O devices with no file system of their own, such as devices that use magnetic tape.
If pushd is not provided with a path argument, in Unix it instead swaps the top two directories on the stack, which can be used to toggle between two directories. The popd command removes (or 'pops', in the stack analogy) the current path entry from the stack and returns to the path at the top of the stack as the new working directory.
