Allow writing file from command line aguments

[avalonwilliams]

Currently to write a compile_commands.json from the output of the command you have to do this:

compdb -p build/ list > compile_commands.json

While this is fine for just using the plain CLI, it is problematic for automating the process in programs that do not use the shell, but call the program directly.

I think that there should be a command line option to write the output to a file, not to stdout, so writing compile_commands.json could be like this:

compdb -o compile_commands.json -p build/ list

Is the issue you're seeing using compdb in a Makefile related to this?

No, using it in a Makefile is fine, however, the problem is mostly with compatibility with certain plugins/ides that don't execute the command in /bin/sh or similar, but call the executable directly.

Fixed in 43a3455.

Thanks for the suggestion.
