MS-DOS Editor (EDIT)

Edit allows a user to view, create, and/or modify their computer files. If you are unable to get this program to work, try typing "path c:\windows\command", if you are using Windows95/98. Type "path c:\dos", if you are using DOS 5.x/6.x/7.x or Windows 3.x. If you still are not able to get edit to work, it may not be on the hard drive, type "dir edit.com /s" at the C:\>. If it says that the file is not found, you may not have this feature. If you are running a MS-DOS version 4.x or lower or you are unable to find "edit.com" on your hard disk drive, you can also use "copy con [filename]" command to create a file.

Once you have entered the above command this will create the file with the name specified. Once you have typed all the lines you wish to be in the file, press and hold "CTRL + Z". This should enter ^Z, once on the screen, press enter and one file should be copied.

The edit command is an external command that is available in MS-DOS 5.x and above, Windows 95, Windows 98, Windows ME, Windows NT, Windows 2000 and Windows XP.

Syntax: edit [switches] [filename]
  • /B - Forces monochrome mode. 
  • /H - Displays the maximum number of lines possible for your hardware. 
  • /R - Load file(s) in read-only mode. 
  • /S - Forces the use of short filenames. 
  • /[nnn] - Load binary file(s), wrapping lines to [nnn] characters wide. 
  • /? - Displays this help screen. 
  • [file] - Specifies initial files(s) to load. Wildcards and multiple file specs can be given.
Examples
  • edit c:\autoexec.bat - This would look at the autoexec.bat. However, if the file is not found, you will have a blank blue screen. When editing this or any file, ensure that you know what you are placing in the files improperly editing the file can cause issues with your computer.
  • edit myfile.txt - This would bring up a blank edit screen, as long as the file is saved upon exit this will create the file myfile.txt.
