stat() is a system call. in linux it is put in a c wrapper and made an
executable. this is not done in unix. if you just want to check the time stamp
on a file, i think this can be done by playing with 'ls' or 'find', etc. of
cause you can write a little program that calls stat(). do a 'man stat' on the
usage.
