Output type options:\n\

-m, --mixed like --windows, but with regular slashes (C:/WINNT)\n\

|
-M, --mode report on mode of file (binmode or textmode)\n\

Path conversion options:\n\

-a, --absolute output absolute path\n\

-s, --short-name print DOS (short) form of NAMEs (with -w, -m only)\n\

-C, --codepage CP print DOS, Windows, or mixed pathname in Windows\n\

codepage CP. CP can be a numeric codepage identifier,\n\
