4DOS
4DOS is a command-line interpreter by JP Software, designed to replace the default command interpreter COMMAND.COM in MS-DOS and Windows. It was written by Rex C. Conn and Tom Rawson and first released in 1989. Compared to the default, it has a large number of enhancements.
4OS2 and 4NT are similar products that replace cmd.exe in OS/2 and Windows NT respectively.
4DOS is most often used as a command-line replacement for the following operating systems:
Since Windows NT and Windows 2000 includes both COMMAND.COM and cmd.exe, 4DOS and 4NT and derivatives can both be installed. Earlier versions of 4OS2 can be run under Windows NT, and OS/2 can run the two DOS and Windows NT shells, all three can be used on Windows NT-type machines and OS/2 multiple boot machines.
Among the many commands, statements and functions in 4DOS and lacking in DOS/Windows 95–98 COMMAND.COM are reading keyboard input and a simpler method of working with colors of screen and text.
The default file extension for 4DOS scripts is .btm.
A graphical version of 4DOS, 4OS2, and 4NT, called Take Command, was released with a feature set corresponding to version 4DOS 5.5, 4OS2, and 4NT 2.5 and updated after this. Development on this line stopped with the corresponding text mode versions. There was a graphical program Take Command/16, for Windows 3.1.
4OS2 is a similar replacement for IBM's OS/2 command interpreter. This was first released at the same time as 4DOS version 4, and has a similar feature set. Like 4DOS, this is released as open source. It appeared in the feature set of 2011's eComStation 2.10, in the freeware os2free project, and is included with ArcaOS.
