Use "strace" To Understand Your Shell (BASH)

Sign up or log in to save this to your schedule and see who's attending!

Using the UNIX command line ("The Shell") and it's many powerful tools is getting less and less common, and in the days of colorful GUIs the shell is said to be too cryptic and no longer usable. Knowing only a few basic concepts of shell operations and behaviour, working on the command line and writing shell scripts can be both easy and very heplful.

With strace it's possible to trace and visualize how programs are started, and it will clearly show you what happens with wildcards, quotings and all those nasty details in daily shell work.

After last year's introduction to strace, Harald Koenig will show in this "hands on" presentation in a command line terminal session (aka "xterm";) how easy it is to see, understand and learn the most important shell principles, and how strace can help you in analyzing the run of a shell script in much more details than "set -x" can do.
