title: The 'command not found' handler
tags: #bash #command-not-found

See [this askubuntu question](https://askubuntu.com/questions/1464106/command-not-found-handler/1464110#1464110).
In summary:
```bash
declare -f -p command_not_found_handle 
```
yields
```bash
command_not_found_handle () 
{ 
    if [ -x /usr/lib/command-not-found ]; then
        /usr/lib/command-not-found -- "$1";
        return $?;
    else
        if [ -x /usr/share/command-not-found/command-not-found ]; then
            /usr/share/command-not-found/command-not-found -- "$1";
            return $?;
        else
            printf "%s: command not found\n" "$1" 1>&2;
            return 127;
        fi;
    fi
}
```
and you can override this to whatever you like.
