Bashing up

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.
