Occasionally, vim on the Raspberry Pi will throw multiple Sorry, the command is not available... errors when using the basic vimrc from amix/vimrc.

This is likely 'cos the vim-gui-common and/or vim-runtime packages are missing. Fix with:

sudo apt install vim-gui-common vim-runtime

Turn off onboard LEDs on Raspberry Pi

Add the following to /etc/rc.local. This has been verified as working on a Raspberry Pi 3 with the caveat that on power up and reboot, the LEDs are on briefly before being disabled.

for led in /sys/class/leds/*
do
  printf "Disabling LED: $led\n"
  sudo sh -c "echo 0 > $led/brightness"
 sudo sh -c "echo none &gt; $led/trigger"

Convert Garmin FIT to GPX

Requires GPSBabel

# Tested in zsh
for f in *.fit; do echo ${f:t:r}; gpsbabel -i garmin_fit -f "$f" -o gpx -F "${f:t:r}.gpx"; done

	#!/bin/bash

	# The following is from the Garmin forums: https://forums.garmin.com/forum/garmin-express/garmin-express-pc/76831-
	# The Garmin Forerunner 220 and 620 (FR220 and FR620) save their activity
	# files with a cryptic name on the watch. Based on Jeff Pethybridge's
	# (ZUKJEFF) analysis and my own findings, these would be the filename codes:
	#
	# Example: 43S64121.FIT
	#
	# Char 1 is year: 3 (2013), 4 (2014) ... Will clash in ten years time!
