In Linux, the command used to copy files and directories is cp. The basic syntax of the cp command is as follows:

cp [选项] 源文件 目标文件

Among them, the source file represents the path of the file or directory to be copied, and the target file represents the path of the copied file or directory. Here are some commonly used options:

• -r or --recursive: used to copy a directory and its contents recursively.

• -i or --interactive: Ask whether to overwrite the existing target file before copying.

• -v or --verbose: Display detailed copy information.

• -u or --update: Only copy the parts of the source file that are newer or do not exist than the target file.

• -p or --preserve: Preserve the attributes of the source file (such as permissions, timestamps, etc.).

The following are some sample usages:

1. Copy files:

 cp source-file.txt destination-file.txt

2. Copy directories and their contents:

  cp -r source-dir/ destination-dir/

3. Copy the directory recursively, retaining the attributes of the source file:

  cp -rp source-dir/ destination-dir/

Please use appropriate options and parameters to perform the copy operation according to your actual needs and target path.
