Here are a couple of useful Bash resources that came upon my radar recently.
First one is Julia Evans’ blog post “Bash scripting quirks & safety tips“. It’s quite introductory, but is has a few useful tips. The one in particular I either didn’t know about or completely forgot mentioned recently is on how to make Bash scripts safer by using “set -e“, “set -u“, and “set -o pipefail“. These go well with another post of mine not so long ago.
The second is Sam Rowe’s blog post “Advancing in the Bash Shell“, which I found useful for all kinds of navigation and variable expansion in Bash command line. Especially the bits on searching and reusing the history.
