    ITYM:

    dates -op1 -op2 file || echo no banana


    Make that instead:

    [ cmd ] || failure

    This makes little sense. Either write

    cmd || failure

    (with cmd and failure being commands), or write

    [ test-cond ] || failure

    with the '[' being another form of the 'test' command

    test test-cond || failure

    and test-cond being any valid test condition.

    There's also other applications possible, like, say,

    [ -n "$(cmd)" ] || failure

    that somewhat resembles your cmd expression above.

    Another post for my notes (about dozen or more of yours now).

    Thanks.
