How can I replace "bash: $COMMAND: command not found" message?

Question

Any help would be appreciated.

Basically, I want to replace:

~]$ obvfake
bash: obvfake: command not found

With:

~]$ obvfake
[*] command not found

Thanks.

bash version 4 introduces a hook for handling missing commands; add the following to your .bashrc file.

command_not_found_handle () {
    printf "[*] command not found\n"
    return 127
}
