cp

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

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

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.
