BacktestTool - batch backtest, import and strategy parameters optimalization

[hasitt]

I'm working on docker and I've been through the install with a few issues. I've tried a few things including installing gcc, reinstalling xcode and upgrading docker. Eventually I had to manually install the File::Copy (the last part of the long CPAN command). So all the dependencies are fulfilled. If I run the backtest.pl it works from my machine but when I run from docker backtest.pl can't be found:

Code:

docker exec -it 50f3d30ab2ba perl backtest.pl
Can't open perl script "backtest.pl": No such file or directory

Have I missed something obvious?
