Answer 1

For inside some directory, this will be use full as it copy all contents from "folder1" to new directory "folder2" inside some directory.

$(pwd) will get path for current directory.

Notice the dot (.) after folder1 to get all contents inside folder1

cp -r $(pwd)/folder1/. $(pwd)/folder2
