question about uefi shell-current working directory and shell-script

[krishnaLee <sssky307@163.com>]

Hi,
I wonder if it is a bug:
I have a usb Fat32-disk,installed with EDK2 shell2.6 or 2.7,
the root directory has a startup.nsh,the startup.nsh has only one line:"cd \",
I boot my cannolake machine with this usb disk,
in the uefi shell,I got a message:"cd: current directory not specified".it means the cwd environment variable was not set when start doing script.


I think it may be  an error,because the uefi shell can find the startup.nsh,why not set cwd(current working directory) before execute this script,so the cd command works fine.
I mention it because I found if I put a uefi application(using efi_shell_protocol to access .\logfile.txt) in this startup.nsh,the uefi application can't access files,
 because I found the efi_shell_protocol need cwd to work too,such as efi_shell_protocol.OpenFileByName().






thank you,
krishna
