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[edit]

-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
cp: illegal option -- -
usage: cp [-R [-H | -L | -P]] [-fi | -n] [-aclpsvXx] source_file target_file
       cp [-R [-H | -L | -P]] [-fi | -n] [-aclpsvXx] source_file ... target_directory

Examples[edit]

cp -a /source/. /dest/
cp -rp /home/origin /home/destination
cp -rp /home/origin/* /home/destination/
cp file.txt file-`date --iso`.txt
