Usage:
NTWHICH <-l | -L | /l | /L | -h | -H | /H | /?> [filename, filename, filename, ...]
Synopsis:
The -l option gives the license. The -h option gives help, as
does the /? option.
NTWHICH searches the path for the first occurence in the path of
an executable consisting of 'filename' plus one of the four command-
line-executable extensions, .COM, .EXE, .BAT or .CMD
The order in which NT will execute files of the same name with
different extensions when found in the same directory is as follows:
1) .COM
2) .EXE
3) .BAT
4) .CMD
Therefore, when searching the path, the first occurrence of a
pair of identical filenames with different extensions is resolved in the
same manner by NTWHICH, e.g., if FOO.COM and FOO.EXE are in the same
directory c:\blah\woof as found in the path,
C:\>NTWHICH foo
will report as follows:
FOO:
c:\blah\woof\foo.COM
NTWHICH accepts multiple filenames. If any filename has an
extension on it, e.g., FOO.ARF, that specific file will be sought, but
again, only in the path.
NOTE: As CMD.EXE has an implicit first element of ".\" (the
current directory) since 'way back in the MSDOS days, NTWHICH treats the
matter the same way: the current directory is searched first.
Bugs:
PATH is limited to about 16K characters. The combined filename
and any single path element is limited to about 4k characters. This
should probably be enough.
