I will try that after this weekend, but I don't hold my breath, since
no amount of '^' characters I tried can protect '*' from being
expanded on XP. E.g.,
D:\usr\eli\data>touch "^foo"
D:\usr\eli\data>touch "^^foo"
D:\usr\eli\data>echocmd ^^*
D:\usr\eli\data>echocmd ^^*
`echocmd ^*'
0: `echocmd'
1: `^foo'
D:\usr\eli\data>echocmd ^^^^*
`echocmd ^^*'
0: `echocmd'
1: `^^foo'
where echocmd.c is shown below.
Evidently, '^' is used by cmd.exe, but is completely ignored by the
MSVCRT globbing code. And since Windows 7 simply removes the quotes
and then globs the result, I expect to see the same on W7. But I will
try that and see whether the theory matches the facts.
#include <stdio.h>
#include <windows.h>
int main (int argc, char *argv[])
{
int i = 0;
printf ("`%s'\n", GetCommandLine ());
while (argc--)
printf ("%d: `%s'\n", i++, *(argv++));
return 0;
}
