SVN doesn't seem to let you revert multiple files with a wildcard (or say if you deleted a whole directory tree in error)?

This works:

svn status|awk '/^D/{system("svn revert " $2)}'

There's probably another way....

This should be a blog post, and I'll make it one when I have more than 5 mins to spare. For instance these examples are hard-coded for my github SSH key, rather than parameterised.

Based on this SO question

Rather than use pass -c to copy an SSH key passphrase to your system clipboard and then paste it at the ssh-askpass prompt (which is not very secure: any program can read the clipboard), you can use an SSH_ASKPASS script to retrieve the passphrase from password store and give it to ssh-add.

Make a script that retrieves the passphrase from pass (which in turn will prompt for a master passphrase if needed, via GnuPG PinEntry):

#!/bin/bash

	define :chiparp do \|notes, duration, c_amp=0.8, c_Hz=30, c_sust_ratio=1, c_step=1\|
	tx=bt(1) # seconds for 1 beat
	in_thread do
	use_bpm 60 # normalise bpm to 1 beat per second
	c_speed = 1.0/c_Hz #the chip speed is better converted from Hz
	count = (duration * tx / c_speed)

	use_synth :chiplead
	use_synth_defaults amp: c_amp, sustain: c_speed*c_sust_ratio,
	attack: 0, decay: 0, release: 0

	#!/bin/bash

	#Add specified SSH keys to the SSH Agent, using SSH_ASKPASS to retrieve
	#each key's passphrase from the Unix password store (pass).
	#This relies upon the keys having the same names in both your key directory
	#and your password store.

	if [[ -z ${1} ]]; then
	echo "$(basename ${0}): no SSH key specified" 1>&2
	exit 1;

	use_bpm 150
	use_synth :tech_saws
	live_loop :crash do
	2.times do
	play_pattern_timed [:C4,:r,:C4,:F4, :G4,:C5,:r,:Bb4], 0.5
	play_pattern_timed [:r,:G4,:r,:G4, :Gb4,:G4,:Gb4,:G4], 0.5
	end

	play_pattern_timed [:F4,:F4, :r], 1
	play_pattern_timed [:r,:F4], 0.5

	#I wanted to hear if Tainted Love and Dr. Who go together... ;-)
	use_bpm 120
	live_loop :metro do
	tick
	cue :beet
	sleep 1
	end

	live_loop :bass, sync_bpm: :beet do
	##\| stop

	#Heard these chords somewhere on the way to work this morning, no idea what the tune was, sorry
	# Anyway they gave me a bit of inspiration as I finished walking to the office, and I hacked this out
	# in about 20 mins.
	#
	# play with the ixi/slicer fx phases, and the ixi res, and start up the bass + simple drums
	#
	# I found that if you wait/sleep at the end of the drum/bass loops, you'll miss the cue for the start
	# of the bar, so that's why the final waits are commented out. Also if you sync at the start, it'll
	# again miss the cue and wait a whole bar. Not sure best ways to resolve this -- just comment where
	# they sync, I suppose.
