EDLIN

EDLIN is a line-oriented text editor, which is included as a standard text editor in MS -DOS and some Windows operating systems. He is regarded as an external DOS command. It offers rudimentary features for editing text files from a command line interface. The operation is done by row numbers and operations with one-character command (for example, deletes the command " 5D ", the 5th row of the current file).

Edlin is also suitable as an interpreter and programming interface for batch files (scripts ). A script is started with:

History

Edlin was developed in 1980 by Tim Patterson of Seattle Computer Products ( QDOS 0.2), Patterson sold even before the operating system to Microsoft. There was only intended as a temporary solution for about half a year. It is a derivative that goes back to the line-oriented editor ed, which is included on Unix and Unix-like operating systems. He was, however, to 4.01 (and thus for 11 years until the release of DOS 5.0 ) as the only standard text editor. During this time he was, apart from the different language versions, apparently never significantly changed or further developed. However, it was integrated with any version of DOS, a copyright notice and a file verification, to prevent starting under the "wrong" version of DOS. Only Edlin from DOS 5 can be 6.x on the DOS versions and 7.00 ( Windows 95a ) and start with the NT - based versions of Windows yet.

As of DOS 5 and Windows versions NT - based Edlin has been replaced by the more modern MS- DOS editor with a window-like semi- graphical interface with menu and scroll bars as the default editor. In DOS 5.0, and in the NT - based versions of Windows ( even in Windows 7, 32 bit ), it is installed as an alternative DOS application.
