I've been doing a lot of bash scripting lately. I haven't really done any bash scripting since, oh, 2007 or so, and nothing to complicated even then, so it's been an interesting learning / remembering experience for me. Hopefully writing it down this time will make it easier next time. Here's a preview of what you'll find here:
- Defining and using variables
- Variable and arithmetic expansions
- Arrays
- If statements
- While loops
- For loops
- Input redirection, output redirection, and pipes
- Regex tools: grep, sed
- Command substitution
- Useful commands
