Since 2017, most code I've written is in support of FSF and GNU, usually system administration related and not public or not publicized. The most generally useful public package I've written is a Bash stack trace and error handling library, Bash Bear Trap, and a Bash Style Guide that talks about Bash error handling.
If you find any of these useful, let me know. Patches welcome, email to ian@iankelling.org
A few of these are mirrored on sr.ht sourcehut account in case that helps people contribute or use them.
