About this class This course presents proven techniques for effectively using key standard UNIX tools and utilities. Through extensive in-class hands-on exercises, you gain the knowledge and skills to adapt the UNIX environment to your particular needs. Who will the lesson benefit? Those who want to maximise the power of their UNIX/Linux system. Knowledge of UNIX or Linux at the level of Course 428, "UNIX Comprehensive Introduction", or Course 143, "Linux Comprehensive Introduction", is assumed. What delegates will learn - Become an expert builder and user of UNIX/Linux tools and utilities
- Employ standard, programmable text filters to manipulate text and data
- Build shell scripts to automate routine tasks
- Achieve significant productivity gains by matching the mix of tools to the task at hand
- Process structured data with awk
