Using pathnames with
internal commands
IVhat are external
:ommands?
Some internal commands can use paths and pathnames. Specifi-
cally, four
commands-copy, dir, del, and type-have greater
flexibility when you specify a pathname after the command.
The formats of these commands are as follows:
copy pathname patbname
If the second pathname is a directory (a path), MS-DOS copies all
the files you specify in the first pathname into that directory, as
in
the following example:
copy \user\pete\*.* sales
del pathname
If the pathname is a directory (a path), all the files in that direc-
tory
are deleted. If you try to delete a path, the prompt "Are you
sure (YIN)?" is displayed. Type Y(for Yes) to complete the com-
mand,
or N (for No) to stop the command. Example:
del \user\pete
dir pathname
The following command displays the directory for a specific
pathname:
dir \user\pete
type pathname
You must specify a pathname (or filename) for this command.
MS· DOS then displays this file on your monitor in response to the
type command. Example:
type \user\emily\report.nov
Any filename with an extension of .com, .exe, or . bat is con-
sidered an external command. For example, files such as
format. exe and diskcopy. exe are external commands. And, because
these
commands are also files, you can create new commands and
add them to MS·DOS. Programs that you create with most languages
(including assembly language) will
be .exe (executable) files.
Note, however, that
when you use an external command, you do
not need to type its filename extension.
