Question: run node in shellscript

I recently got this error using `nyc` with `child_process.execFileSync('bash', ['-c', 'node --version'])` in windows7 with git bash:
```
/c/Users/xxx/.node-spawn-wrap-11344-5af67802646a/node: C:\Program: bad interpreter: No such file or directory
```
I feel this error is related to the `README.md` piece:

```
In order to handle cases where node is invoked in a shell script, the PATH environment variable is modified such that the the shim will be run before the "real" node. However, since Windows does not allow executing shebang scripts like regular programs, a node.cmd file is required.
```

I don't know how does it mean by `a node.cmd file is required`. Could you help?
Thanks in advance.
