command is shell builtin, and all modern shells knows the 

    command -v name >/dev/null construct.

and works similarly, hash is also shell builtin, but in ksh it returns
0 even the name in question is not found. So when someone uses parts of
our shell scripts as an example when they do their own they have better
change of succeeding. which(1) is not shell builtin, usually 
located at /usr/bin.
