Course Description
In Linux, Bash scripting is a fountain of computing power. It is part of one of the most powerful and efficient operating systems in computing. The basis of shell scripting is in automating common tasks as well as creating scripts to secure, backup, and manipulate large amounts of data. Bash scripting is one of the most profound tools in your Linux arsenal. The ability to automate various repetitive tasks in a multi-threaded environment can save companies countless man hours. In this course, you will learn Bash scripting with commands, variables, functions, and even regular expressions.
What You'll Learn
- Write Bash shell scripts using commands, variables, functions, and regular expressions
- Distinguish between Bash, Korn, and C shells and compare a Bash script to a batch file
- Work with environment and user-defined variables, including variable types and scoping
- Apply comparison operators, math operators, and string tests in Bash
- Build conditional logic with if-else-fi, elif, while loops, and for loops, including nesting and ranges
- Automate commands using pipes and redirectors, redirect stdout and stderr, and modularize work with functions
Key Takeaways
- Bash scripting automates common, repetitive tasks such as securing, backing up, and manipulating large amounts of data.
- Automating repetitive tasks in a multi-threaded environment can save companies countless man hours.
- The course covers shell scripting basics including commands, variables, functions, and regular expressions.
