How to extract audio from video with ffmpeg, into separate files
REM This script will check all MP4 files in the current folder
REM and process them to extract audio into separate files (M4A).
REM The audio files use the same file name as the original video file, with a number, and the M4A extension
REM This is a batch file, to be run on Windows, in Command Line.
REM For Linux, see the "extract-audio.sh" gist below
REM In this example, there are 2 audio tracks, which get split out to 2 separate audio files.
REM The original video file remains unchanged.
REM If you want have a video file with more than 2 audio tracks,
REM just add more "-map 0:a:0 -c copy "%~na audio track 1.m4a"" sections:
REM -map 0:a:0 -c copy "%~na audio track 1.m4a"

Use Mosh on Windows from the Command Prompt

Hi all. After wanting true color support in Mosh (to use Brow.sh), I also wanted to integrate it more tightly with Windows. Since I reckon more people will be wanting to accomplish this, here is a guide.

  1. Install Linux Subsystem for Windows if you haven't already (https://docs.microsoft.com/en-us/windows/wsl/install-win10) (I use Ubuntu)
  2. Make sure you can execute bash from a CMD prompt.
  3. Go into the bash environment by executing bash ~ in CMD prompt
  4. Install Mosh-dev (for up-to-date version) from https://launchpad.net/~keithw/+archive/ubuntu/mosh-dev by doing sudo add-apt-repository ppa:keithw/mosh-dev then sudo apt-get update
  5. Create a new mosh.bat file on your Desktop with the following contents
@echo off
