When creating excessively long oneliners (you know, the kind that should actually be a script, because you know you're going to find a use for it in a few weeks), the following key combo is golden:

    ^x ^e

It opens up the exported EDITOR with a tmp file containing whatever is on the command line.

Using SSH, especially on campus/in a train/other places where a wifi connection doesn't long, mosh is really a godsend. In places where mosh isn't practical or available, the following combos are really good to know:

    <RETURN> ~ .    # end ssh connection
    <RETURN> ~ ?    # show available commands

Paired with autossh which will reconnect by itself, it really takes the pain out of traveling while doing remote work.

Oh, and when you need to know what the decimal value of 0x65433 is, it's good to know that bash can do stuff like that:

    $ echo $((16#65433))
    414771

Reading the bash man page is not a bad idea in itself...
