How to add more to Git Bash on Windows

Git for Windows comes bundled with the "Git Bash" terminal which is incredibly handy for unix-like commands on a windows machine. It is missing a few standard linux utilities, but it is easy to add ones that have a windows binary available.

The basic idea is that C:\Program Files\Git\mingw64\ is your / directory according to Git Bash (note: depending on how you installed it, the directory might be different. from the start menu, right click on the Git Bash icon and open file location. It might be something like C:\Users\name\AppData\Local\Programs\Git, the mingw64 in this directory is your root. Find it by using pwd -W). If you go to that directory, you will find the typical linux root folder structure (bin, etc, lib and so on).

If you are missing a utility, such as wget, track down a binary for windows and copy the files to the corresponding directories. Sometimes the windows binary have funny prefixes, so

Install single-user SSH daemon as Windows service with pure msys tools

WARNING This approach does not enable impersonation. Thus, only a single user account is able to connect through ssh - the same user we use for running the Windows service. At time of writing it seem to only be possible with cygwin or msys2 to achieve multi-user support for sshd under Windows. E.g. https://ghc.haskell.org/trac/ghc/wiki/Building/Windows/SSHD

Requirements

Latest Git for Windows. I tried it with v2.6.0. (Note: with v2.5.3 sshd tried to load authorized keys from /c/.ssh instead of ~/.ssh).

Create unprivileged sshd user

Converting Audio into Different Formats / Sample Rates

Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma

You can get the list of supported formats with:
ffmpeg -formats

You can get the list of installed codecs with:
