Run cygwin command from windows command line

Question

I am trying to make PhpStorm run vagrant rsync when files are changed, because built-in rsync-auto fails with my deep directory structure. I am able to setup watcher in PhpStorm settings, but I don't know how to run it correctly. There problem is that when I run vagrant up or vagrant rsync from windows command line, I am getting different errors from wrong path to arguments issues, so I decided to run it under cygwin and it works now. So, I need a solution to run cygwin from command line and execute command in it.

What I tried:

C:/cygwin/bin/bash vagrant rsync

Getting error:

C:\Program Files\Vagrant\embedded\bin\ruby.exe: No such file or directory -- /cygdrive/c/Program Files/Vagrant/bin/../embedded/gems/gems/vagrant-1.6.5/lib/vagrant/pre-rubygems.rb (LoadError)

Tried:

bash vagrant rsync

Error:

rsync: connection unexpectedly closed (0 bytes received so far) [Receiver]
rsync error: error in rsync protocol data stream (code 12) at io.c(605) [Receive
r=3.0.9]
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(235) [sender=
3.1.1pre1]

Trying to find out why output is different:

C:\>where bash
C:\Program Files\Git\bin\bash.exe

So msysgit is used in second case.

Command:

C:\cygwin\bin\mintty -e vagrant sync

Output: nothing. Window opens and closes immediately.

Use c:\cygwin\bin\run.exe to launch cygwin processes from windows cmd.exe
