In case someone else encounters this, I wrote up a bit more detail on opening a Git-aware command prompt/shell in the Local toolchain topic mentioned above:
As @deltahat suggests, GitHub for Windows sets up everything necessary to open a Cmd, Git Bash or PowerShell shell that recognizes commands like rm and mkdir.
Quick way to use it:
- Tap the Windows key
- Type "git shell" - just "git sh" should be enough - then press
<Enter>
Bam! You're now in a Git-aware shell. The above works for Windows 7 and Windows 8.x.
If you don't like the type of Git shell that opened, change the default by going into the GitHub for Windows app - aka GitHub - and selecting tools then Options... where you can change the default shell to something else.
