Last night there was a phpGG (dutch php user group) meeting in Utrecht with a presentation by Lorna Jane titled ‘Linux-Fu’. Attended by about 10 people, console basics � tricks were addressed. I’m not unfamiliar with Linux so the basics weren’t that new. For development I mainly use IDE’s so I just use the console to edit the occasional config file, create some symlinks, that kind of stuff. For those tasks I find myself sticking to set of commands I’ve learned and just occasionally taking the time to do an in-depth google search for better ways to get the job done. So with regard to linux shell trickery there are things to learn for me. Neat timesavers:

Switching between current and previous directory:

cd -

Going home can be done without the ~:

cd

How ‘grep’ can beat your IDE. I’ve been playing around a bit and this is really a quick way of finding all classes within a directory that implement an interface (and it’s fast!):

grep -i -r 'class ' . | grep implements

And there’s ‘screen’. Very useful for handling multiple terminal sessions without the risk of losing them all due to a connection hick-up. Lorna has some config examples on her site.

So not all was new but there were definitely some nice starting points to investigate further.
