    Nope. Think of the command which produces a really long output...do you
    want it to be saved in memory?

    Anyway, there are a several solutions to your problem. First, as it was
    mentioned here already, you can use tee or output redirection (> or >>).
    Second, you can use script command (see 'man script' for details).
    Third, you can save command output into a variable, like this:

    OUT=`find /`

    and use it like any other shell variable.
    (Fourth;) You can even make a short script, like this:

    #!/bin/bash
    # so - Save Output. Saves output of command in OUT shell variable.
    OUT=`$*`
    echo $OUT

    and use it like this
    so find . -name myfile

    And the last thing is to copy-paste from your terminal.
