Together with CPU’s often being “fast enough” I would expect that the macbook air kind of formfactor becomes way more of a norm than it used to be. Apple was ahead of the curve, and I absolutely have higher expectations of the hardware I use than the average user probably does, but at the same time I’m convinced that the notebook market will finally get where I think it should be. Sure, some people will still want to use the big clunkers, but making a good thin-and-light machine is simply not going to be the technical expensive challenge it used to be.

In other words, we’ll take the whole Macbook Air formfactor for granted in a few years. It’s been done, it used to be pretty revolutionary, it’s going to be pretty standard.

It *did* take a lot longer than I thought it would take, admittedly. I’ve loved the thin-and-lights for much longer than the Macbook Air has existed. It’s not like Apple made up the concept – they just executed well on it.

PROMPT_COMMAND lets you specify a command that bash will run every time it shows you a fresh command prompt, i.e. every time you run a command and the command finishes. So the above tells bash to read any new lines that have appeared in ~/.bash_history since the last time it read it, and then append the last-run command from this terminal to ~/.bash_history, every time you run a command.

So now, if you type a command in one terminal, and want to access it via the history of another terminal, run a command in the other terminal (or just hit Enter) to trigger PROMPT_COMMAND, and then your history will be nicely up-to-date and synchronized with any other terminals you have open. Almost certainly, you'll never notice the tiny bit of overhead caused by bash constantly reading and writing to ~/.bash_history.

See man bash for more info on the history builtin.

Below is the collection of Linux command line tips which I’ve found useful for Linux users. To get more information about the command mentioned below just open your terminal and type man <command>.

Suppose you have a long-running task (for example, compiling a large program) that you need to run, but you also want to get some other work done. Linux lets you start a task in the background and keep on doing other things from the command prompt.

We will see in this article how to send commands in the background, then return them to the foreground, and make sure that also closing the current shell or terminal the process doesn’t remains tied to the session but continue to work.

An alternative to these command is using screen, as read in a former article, but now let’s seethe command bg and the spacial character &

SSH has many features which are helpful when working regularly with files on remote servers; together they can give a vast increase in productivity over the bare use of SSH. If you regularly use SSH, it’s worth spending a little time learning about these and configuring your environment to make your life easier.
