A Firefox nightly version is successfully built on my PC but I still can’t execute the xpcshell follow the steps from [here](https://developer.mozilla.org/en-US/docs/Mozilla/Tech/XPCOM/Language_bindings/XPConnect/xpcshell). My OS is window 7. The error message is

> bash: ./run-mozilla.sh: No such file or directory

But I could execute the xpcshell test by

> ./mach xpcshell-test

Any suggestions will be appreciated. Thanks.

@jorgev, Thank you. I have found out the reason and the relative document of xpcshell is updated too.
