Re: How to call something when a command is not found?

[Peng Yu]

My question was to Marco. You don't need to reply it.

command_not_found_handle does call /usr/lib/command-not-found. I don't
understand why there is a difference in the output when I directly
call /usr/lib/command-not-found or let bash call
command_not_found_handle.

$ type command_not_found_handle
command_not_found_handle is a function
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
}
