Hello guys Today i have a topic which we all know !! All Ms-Dos or Command Prompt Commands !! What's Hot in this post was i explane all Commands and try to describe the use of the command. We all know these commands are very useful for batch programing. I was just learning about batch programming but don't know much more commands of command prompt and then i was found all these command's. Let me show you !!!!
In the list below, commands that can accept more than one file name,
or a file name including wildcards (* and ?), are said to accept a filespec parameter. Commands that can accept only a single filename are said to accept a filename
parameter. Additionally, command line switches, or other parameter
strings, can be supplied on the command line. Spaces and symbols such as
a "/" or a "-" may be used to allow the command processor to parse the
command line into file names, file specifications, and other options.
The command interpreter preserves the case of whatever parameters are
passed to commands but the command names themselves and filenames are
case-insensitive.
While many commands are the same across many DOS systems (MS-DOS, PC DOS, DR-DOS, FreeDOS, etc.) some differ in command syntax or name.
Lets Start The commands List

Renaming the XCOPY program file to MCOPY under MS-DOS 3.2, the command will no longer ask for confirmation if the target was meant as file or directory. Instead, it will then automatically assume the target to be an directory, if the source was given as a directory or as multiple files or was ending on "\".
So..... This is the full index or list of command prompt / ms-dos commands hope this post help you the source of these commands was wikipedia.
