Many times you’d like to see the progress of a copy but sadly `cp` doesn’t have that feature.
Many posts online will show bash scripts that pipe `cp` into `grep`/`awk`/etc or use tools like `pv`. Alas, there is a much more simple way. Use `rsync`.
rsync -a --progress SOURCE_FOLDER DESTINATION_FOLDER
Throw the `—stats` flag for some stats after the transfer is done.
rsync -a --stats --progress SOURCE_FOLDER DESTINATION_FOLDER
