cp[1] command is used for copying files and directories. It lacks progress bar indicator[2], but you can use progress -w or progress -m command to display the percentage of copied data or use rsync[3] command.

Ansible also includes a cp module with limited scalability (>hundreds of files) [4]

Options

-a, --archive
-l, --link hard link files instead of copying
-p same as --preserve=mode,ownership,timestamps
-R, -r, --recursive
--reflink[=WHEN] control clone/CoW copies. --reflink=always
-v verbose, showing files as they are copied.
cp --help
