Related problem

On Windows, if I set the ComSpec environment variable (which specifies the command interpreter) to C:\Users\Victor\.cargo\bin\nu.exe, and then call libc::system (Microsoft docs) with whatever given command, I get the following error message:

Error: nu::shell::file_not_found (link)

  × File not found
   ╭─[source:1:1]
 1 │ nu
   · ▲
   · ╰── Could not access file '/c': "The system cannot find the file specified. (os error 2)"
   ╰────

I suspect this happens because the libc::system call expects the command interpreter to respond to the /c flag by running the given command. Unfortunately, nushell interprets the /c as a script file argument and attempts to open it, resulting in the above error message.

Describe the solution you'd like

Support /c as an alias for the -c argument on Windows (or all platforms, if that's easier).

Describe alternatives you've considered

研究方向: Investigate how the current argument parser handles the ` c` flag in `nu/src/main.rs` or `crates/nu parser/`. Consider adding an alias for `/c` on Windows by checking platform and mapping to the existing ` c` option. Review related issues or PRs for similar platform specific argument handling.
