Effective Bash scripting for software developers
I’ve been asked many times about my shell scripts and things I’ve automated, as I’ve recently shown in a video about things I’ve automated on my system. I’ve created another video on how to effectively write Bash scripts for regular developers, who aren’t experienced on the sysadmin side of things.
First and foremost, I wouldn’t consider myself a shell scripting expert, but there are so many pragmatic and effective things that make our lives easier, that it would be a shame to not use the power of the command line and its possibility to automate things on our system.
In the video I’m sharing some Bash scripting examples and tips that will hopefully improve your scripts. You can find a full example script to copy-and-paste from on GitHub.
In the video I’m showing:
set -euo pipefailoption
- Navigating to the script’s location with
- Using Bash traps
xargs, piping, and loops
- Number formatting with leading zeros
- Waiting and health checks
- Handling PID files
- Example script on GitHub
- Dotfiles repository
