I’ve been tuning Scout’s Apache setup lately. To start, I looked at the output of:
...but this only provides an instant snapshot. I wanted to watch the results over a longer period of time:
...but this generates a lot of output and I was only concerned with the number of idle workers. I wanted to make sure there were enough around during peak periods:
Perfect. One line of output and just the bits I cared about:
That’s why I love the Linux toolset: 4 single-purpose commands designed to work together.
My tools outside the terminal have come to resemble those within it. My latest update was a switch to an 11” MacBook Air as my development computer. The Air has limitations – a small screen, weak speakers, etc – but it’s perfect for the core work I do every day. Apps and files open quickly. Search is fast. At 2 lbs, there’s no burden carrying it around.
It’s easy to combine the Air with other tools when I need it to do more: an external monitor for a larger display or an Airport connected to my stereo for great sound.
Linux’s tools are usable by themselves but extendable – the 11” MacBook Air is in the same vein.
