Thanks for trying it.

Unfortunately, I can't find the time to dig into this now. And, I think
it's likely related to ShellPkg anyway. Can you please help by filing a
BZ for ShellPkg, and/or bisecting the issue (assuming you remember the
same command working at some point)?

... I observe that the least recent commit that affected "Cp.c" with any
potential to break it like this could be

commit fbd2dfadfe6fb16ab7b49fca3764e05e65d97b8a
Author: Qiu Shumin <shumin....@intel.com>

    ShellPkg: Follow spec to remove the last '\' char in return name of
GetCurDir().

but that commit is more than a year old now... So I'm not sure. Could be
one of the underlying helper functions. Time to pull out GDB and single
step the code? :)

Thanks!
Laszlo
