With NodeJS/npm how can I run Linux command in Windows and others?

I created a nodejs tool with Grunt that uses find command in Linux. When I run the module in Windows, the find command is different, so I won't get the same result.

This is the grunt task:

    exec: {
        collectJSON: {
            cmd: "find " + PROJECT_PATH + " -path '**/" + DIST_REGION + "/**/*.json' ! -name '_*'",
            stdout: false,
            callback: function (error, stdout, stderr) {
                grunt.file.write(jsonPath, stdout);
            }
        }
    },

I heard that npm is a package manager and it can take any "program" as our module's dependency, so I was wonder if there is any npm package can help me to run the find command in Windows (and others environment as well).

Any help would be appreciated!
