Advanced Bash scripting Home

Welcome to the home page for the CBRS Advanced Bash Scripting short course 9am - noon on Wednesday May 6 and Friday May 8.

This hands-on short course will cover advanced topics in writing bash shell scripts, providing tips, examples and best practices for creating robust "pipeline scripts" that execute multiple processing steps. Topics include defining functions, argument processing and defaulting, subtleties of Unix stream and text manipulation, and error checking. We will also explore effective use of Unix tools such as cut, sort, read, awk, grep, sed, and perl.
