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, --linkhard link files instead of copying-psame as--preserve=mode,ownership,timestamps-R, -r, --recursive--reflink[=WHEN]control clone/CoW copies. --reflink=always-vverbose, 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
- cp using Bash brace expansion:
cp /etc/httpd/httpd.{,.BAK}
