syncthing.sh: Syncthing + tmux control

This is a simple script to control syncthing. It is possible to also source this script in 'sh'-like shells (tested in dash, bash and zsh). When used as a script it accepts a number of subcommands; if sourced, a number of syncthing_* functions are defined.

# Via: https://sts10.github.io/2018/11/27/syncthing-and-tmux.html
# Changes to `ss` and `se`:
#   - Start session with command on `new-session`: avoids creating a shell
#     session just for `syncthing`; also use only `kill-session` instead of
#     sending keys.
#   - Test if the sessions exist (or don't exist) before creating/killing them.

HIBP Pwned Passwords Awk splitter

This Awk script splits pwned-passwords-1.0.txt.7z (and updates) into 256 files xz compressed files, by hash prefix (2 digits).
The script assumes the format of the input file is one hash per line.

It can be ran for more than one pwned-passwords-*.txt.7z file, such as pwned-passwords-update-1.txt.7z as long as Troy keeps the format consistent.

Requires 7z (p7zip), and GNU Awk (tested with
