Eli> You can easily write it yourself, using the library function

Eli>   #include <stdio.h> #include <stdlib.h> #include
Eli> <libc/dosexec.h>

Eli>   int main (int argc, char *argv[]) { char
Eli> full_path[FILENAME_MAX]; extern char **environ;

Eli>      if (argc <= 1) { printf ("Usage: %s progname\n", argv[0]);
Eli> return 0; }

Eli>      if (__dosexec_find_on_path (argv[1], (char **)0, full_path)
Eli> == NULL && __dosexec_find_on_path (argv[1], environ, full_path)
Eli> == NULL) printf ("%s: Command not found\n", argv[1]); else printf
Eli> ("%s\n", full_path);

Eli>      return 0; }
