Command-Line Kung Fu: White Belt

Accepted Session
Long form
Scheduled: Thursday, June 18, 2009 from 1:45 – 3:30pm in Broadway


Come and learn some useful command-line short cuts and shell idioms that will make you vastly more productive in a Linux or Unix shell. Time permitting, we'll even play "stump the expert", so bring your thorniest shell problems.


I teach Linux/Unix skills to hundreds of students every year. Many of them are relatively inexperienced with the Unix command line and I see them getting frustrated or taking round-about approaches to solving problems, when in reality just knowing a few simple tricks would make them vastly more productive.

Topics covered include:
- Command line history and tab completion skills
Fun with find and xargs
- Loop constructs
cut vs. awk
— sort and uniq

The talk is interactive and full of live demos. Students can bring their own laptops and play along.
