Output type options:\n\

\n\

-d, --dos print DOS (short) form of NAMEs (C:\\PROGRA~1\\)\n\
|
|
-m, --mixed like --windows, but with regular slashes (C:/WINNT)\n\
|
|
-M, --mode report on mode of file (binmode or textmode)\n\

|
-u, --unix (default) print Unix form of NAMEs (/cygdrive/c/winnt)\n\

-w, --windows print Windows form of NAMEs (C:\\WINNT)\n\

Path conversion options:\n\

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

-l, --long-name print Windows long form of NAMEs (with -w, -m only)\n\

-p, --path NAME is a PATH list (i.e., '/bin:/usr/bin')\n\
|
|
-U, --proc-cygdrive Emit /proc/cygdrive path instead of cygdrive prefix\n\
|
|
when converting Windows path to UNIX 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\
