Vim (/ v ɪ m / ⓘ; [5] vi improved) is a free and open-source, screen-based text editor program. It is an improved clone of Bill Joy's vi.Vim's author, Bram Moolenaar, derived Vim from a port of the Stevie editor for Amiga [6] and released a version to the public in 1991.
File deletion is the removal of a file from a computer's file system. All operating systems include commands for deleting files (rm on Unix and Linux, [1] era in CP/M and DR-DOS, del/erase in MS-DOS/PC DOS, DR-DOS, Microsoft Windows etc.). File managers also provide a convenient way of deleting files. Files may be deleted one-by-one, or a whole ...
vi (pronounced as distinct letters, / ˌ v iː ˈ aɪ / ⓘ) [1] is a screen-oriented text editor originally created for the Unix operating system. The portable subset of the behavior of vi and programs based on it, and the ex editor language supported within these programs, is described by (and thus standardized by) the Single Unix Specification and POSIX.
ex was eventually given a full-screen visual interface (adding to its command line oriented operation), thereby becoming the vi text editor. In recent times, ex is implemented as a personality of the vi program; most variants of vi still have an "ex mode ", which is invoked using the command ex , or from within vi for one command by typing the ...
The command is available for various operating systems including DOS, Microware OS-9, [1] IBM OS/2, [2] Microsoft Windows [3] and ReactOS. [4] It is analogous to the Unix rm command and to the Stratus OpenVOS delete_file and delete_dircommands. [5] DEC RT-11, [6] OS/8, [7] RSX-11, [8] and OpenVMS [9] also provide the delete command which can be ...
Select all in focused control or window Ctrl+A: ⌘ Cmd+A: Ctrl+A: Ctrl+x, then h: ggVG, unlikely ever needed as most commands take an optional range parameter. % means "all in focused windows" here so e.g. to copy all the text, use:%y: Ctrl+A: Cycle through installed keyboard languages / input methods
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]
Similar problems can transform cp and mv into dangerous weapons, and misuse of the > redirect can delete the contents of a file. This is made more problematic by the fact that many UNIX commands differ in name by only one letter: cp, cd, dd, df, etc.
