Here are projects that I actively work on. All of them are POSIX shell scripting related.

They are:

beadm(8) – manage ZFS Boot Environments on FreeBSD
automount(8) – mount removable media on FreeBSD
lsblk(8) – list block devices on FreeBSD

Below is detailed information about these projects.

I started the beadm(8) in 2012 and its developed/supported today. In the meantime the FreeBSD project created its own tool called bectl(8) that aims to implement beadm(8) in the C language.

The automount(8) was started in 2013 and lives still today. Its used as chosen automounting solution in the GhostBSD distribution. The automount(8) uses FreeBSD’s devd(8) events for the mount/unmount actions. It currently supports most popular file systems such as:

NTFS
MSDOS
exFAT
EXT2
EXT3
EXT4
UFS
XFS
HFS
MTP
ISO9660

The automount(8) source is available on GitHub here:

lsblk(8)

The lsblk(8) was started as proof of concept in 2016 but finally in 2019 I got back to it and made it usable/production ready.

I also made dedicated article about lsblk(8) here:
