I'm a bit late but I add my own solution: put these programs in your PATH infact you can use gnuwin32 or UnxUtils as I've done since years.

They are really useful and make the poor cmd.exe experience a bit easier to survive to. That said a plain perl solution is by far better in terms of portability. In your PATH order matters:

C> path

PATH=
C:\EX_D\ulisseDUE\perl5.26.64bit\perl\site\bin;     # strawberry perl 
+portable 
C:\EX_D\ulisseDUE\perl5.26.64bit\perl\bin;          # strawberry perl 
+portable
C:\EX_D\ulisseDUE\perl5.26.64bit\c\bin;             # strawberry perl 
+portable
C:\EX_D\ulisseDUE\bin\UnxUtils\usr\local\wbin;      # <---------------
+-------- UnxUtils
C:\WINDOWS;                                         # OS
C:\WINDOWS\system32;                                # OS

C> ls C:\EX_D\ulisseDUE\bin\UnxUtils\usr\local\wbin | grep -E "grep|mv
+|cat|rm"

agrep.exe
cat.exe
egrep.exe
fgrep.exe
grep.exe
mv.exe
mvdir.exe
rm.exe
rman.exe
rmdir.exe
zcat.exe

Just one big caveat: be sure to have the right make (or dmake, gmake..) in front in your path:
