- 

    var gulp=require('gulp'),         gutil=require('gulp-util');     gulp.task('default',function(){      gulp.src('g:\node\node_modules\npm\test\gulpfile.js').pipe(gulp.dest('g:\node\node_modules\npm\test\sample'));          return gutil.log("inside");         });

i'm beginner gulp.js . have tried cpoy file source loaction destination location. doesn't show errors. file not copied in destination location. tried different locations still doesn't work.
