Unix Workshops

Jump to navigationJump to search

What is it?

It's pretty simple. This is a proposal for weekly free Unix workshops to be held in the space. It'll give people a chance to learn some awesome skills from one another, and discuss any cool new stuff you've been playing with over the past week.

When is it?

Usually Every Tuesday at 19:30 But see meetup for changes.

What to expect

Expect a mixed-bag of Unix tricks, shown off by whoever happens to be about. Whether you're a beginner or a self-proclaimed 'wizard' - you're sure to learn something new.

Also, bear in mind that when we say 'Unix', we mean 'UNIX-like operating systems' This definitely includes Linux, but be prepared to play around with some other interesting operating systems such as the 'BSDs (FreeBSD, NetBSD, OpenBSD), Solaris, ancient Unixes (SysV and the like), and any other similar OSes that are fun to learn about.

The structure of the workshops will generally be along the lines of:

"I have a problem X to solve with the command line. How do we find the solution together?"

What will I learn?

  • What a Unix is, and why you'd want one.
  • How to slice, dice and throw away mice.
  • How to smoke a (Unix) pipe
  • TCP/IP - Internet style.
  • How to use your new-found skills to attract sex partners from all across the world.
  • Something new, each week!

What do I need?

  • A laptop - preferably with around 15GB free HD space for playing with VMs.
  • Some kind of virtualization software. http://virtualbox.org is pretty cool.
  • Something for taking notes with.
  • A suitable amount of curiosity

  • Solution: strace -f -p `pgrep -U alon libvirtd` -e trace=open 2>&1 | grep /image
