There is. Look at `set -h'.
Since this only happens when you run a command found using a PATH lookup,
causing it to be hashed, then explicitly create a command of the same
name and install it in another directory in PATH, I recommend that you
run `hash -r' after you install the second command. This will avoid the
problem while retaining the benefits of hashing.
