Edlin was created by Tim Paterson in two weeks in 1980, for Seattle Computer Products's 86-DOS (QDOS)[3] based on the CP/M context editor ED,[4][5] itself distantly inspired by the Unix ed line editor.
Windows 95, 98 and ME ran on top of an embedded version of DOS, which reports itself as MS-DOS 7.
However, unlike most other external DOS commands, it has not been transformed into a native Win32 program.
When finished entering lines, Ctrl-C returns to the edlin command prompt.
A GPL-licensed clone of Edlin that includes long filename support is available for download as part of the FreeDOS project.
