The internet is full of advice about how to change the caps lock key into a backspace key (a useful practice that originated with Colemak), but a lot of instructions are complicated or outdated.

After *lots* of searching for something that still worked on Ubuntu 14.04, I finally found that this simple command is sufficient and takes effect immediately.

(Found at: http://www.howtogeek.com/194705/how-to-disable-or-reassign-the-caps-lock-key-on-any-operating-system/ )

alias ...="awk '{fflush(); printf \".\"}' && echo \"\""

If you're running a command with a lot of output, this serves as a simple progress indicator.

This avoids the need to use `/dev/null` for silencing. It works for any command that outputs lines, updates live (`fflush` avoids buffering), and is simple to understand.

sysctl -a | grep boottime | head -n 1
ffmpeg -i "input.mts" -vcodec copy -acodec pcm_s16le "output.mov"

This *does not change the video encoding*, so it's fast (almost purely I/O-bound) and results in a file of nearly the same size.

However, OSX (and possibly other programs) will more easily play/seek the file when wrapped as MOV. For example, you can QuickLook the resulting file.

This basically does the same as the commercial ClipWrap program, except using the free program ffmpeg.

touch -r "source_file" "destination_file"
alias t="tee >(pbcopy)"

Very convenient to for sending data to the clipboard for processing.

However, note that tee will affect the buffering of the output (stdout won't be update very live).
