MS-DOS

DOS and DOS-like commands are still usable in modern versions of Windows, and can sometime be the only way to accomplish a given task.

go to start, double click a folder like "programs" and go up a folder to get to the c:\ drive... then navigate to c:\windows\system32\. copy cmd.exe to desktop or my docs and rename "cmd.exe" to "calc.exe" or "notepad.exe" because it will think that you are trying to run those programs.

Under MS DOS, interrupts originate with the central processing unit (CPU). The CPU recognizes issues in applications and stops them and sometimes restarts them in order for them to function properly. Sometimes it shut the application down entirely.

The 'ls' command has many switches and options, especially depending on which version of Unix or Linux you are talking about. The best way to find out is to try either:

man ls

info ls

ls --help

depending on the system.

archive

ren c:\test.txt test2.txt

Results: file in drive c:\ will be renamed to test2.txt

To copy directory, you need to run xcopy command.. You can not copy directory with copy command..

xcopy c:\*.* /s/e a:\

Example 1 1. @echo off
2. set /p answer=Do you wish to continue? (Y/N):

2. :start
3. cls
4. set /p answer=Do you wish to continue? (Y/N):
5.
6. if %answer% == Y goto G
7. if %answer% == y goto G
8. if %answer% == N goto H

Open Notepad and enter this in, then save it as "test.bat". Then open it and it will work like a charm.

You can recover your file by undelete command:

undelete <filename>

This is used to load as much of MS-DOS as possible above the 640k barrier. This leaves as much free conventional RAM for older programs as possible.

A move command is simply a copy command which deletes the original once it's finished.

MS-DOS was not designed for networking, and doses not come with any tools to do so by default.

FILE* f

f = fopen ("file name", "br");

... fread (f, ...);

fclose (f);
