If you are a command-line kind of guy or gal, NT 4.0 provides a number of
command line program enhancements useful to the NT user.
CD /D changes the current directory and current
drive at the same time. As an example, assume that my current drive is D: and my
current directory on C: is the root directory. If I type “cd
/d c:\downloads” my current drive will become C: and the current
directory on C: will become c:\downloads.
MD can now create multiple levels of directory in a
single command. Assume I have no directory called C:\jim. If I type “md c:\jim\fred“. NT will create a directory called \jim and
then create a subdirectory under \jim called fred.
RD /S does a complete tree delete. “rd /s \jim” will remove directory \jim, even if there are
sub-directories and/or files in \jim.
DEL /S can delete in sub-directories. For example,
“del /s *.txt” will delete all text files in either the
current directory or any sub-directory of the current directory.
FOR /D – Makes wildcards match directory names
instead of filenames.
FOR /R – Walks the directory recursively , executing
the FOR command in each directory of the tree.
FOR /L – Equivalent to a BASIC FOR/NEXT loop.
In addition, access to FOR variable references has been enhanced. If you
write batch files, run HELP FOR from the command line
to see all the new features of this command. To see the complete list of
commands that have been enhanced in NT 4.0, enter CMD
/? on a command line. For example, to find out what the proper syntax for
the FOR command is, type for /?
