Answer by mcExchange for How to add more commands to Git Bash?

The above instructions are slightly outdated. Here is what recently worked for me. Use linux to download and extract necessary files:

sudo apt-get install zstd  # download unpack tool# get rsync and necessary librarieswget http://repo.msys2.org/msys/x86_64/rsync-3.2.2-1-x86_64.pkg.tar.zstwget http://repo.msys2.org/msys/x86_64/libzstd-1.5.0-1-x86_64.pkg.tar.zstwget http://repo.msys2.org/msys/x86_64/libxxhash-0.7.4-1-x86_64.pkg.tar.zst# unpacktar -I zstd -xvf rsync-3.2.2-1-x86_64.pkg.tar.zsttar -I zstd -xvf libzstd-1.5.0-1-x86_64.pkg.tar.zsttar -I zstd -xvf libxxhash-0.7.4-1-x86_64.pkg.tar.zst

now copy everything to Windows...for example MinGW/bin or Git/usr as explained above
