I don't know what is "standard". I can tell that cmd.exe aliases have
their own subtle limitations. E.g., they cannot appear after the
pipe, as in "SOMETHING | fgrep FOO" (if "fgrep" is an alias). Aliases
are only recognized in the SOMETHING part, i.e. before the pipe. For
this reason, I stopped using them on Windows almost entirely.

CMD.EXE can run scripts ("batch files"), which can be quite
sophisticated. But the features you can use in these scripts are not
powerful enough to do everything a Posix shell script can do, even a
simple script such as 'fgrep'. There are also subtleties with
invoking batch files, in particular with quoted arguments and with
some special characters like ',' and '='. IOW, you get a script that
works fine in 97% of use cases, but surprises you in the other 3%. A
compiled program avoids all that, and "just works".
