Common linux Command series-cp copy files and folders

Provides various official and user-released code examples. For code reference, you are welcome to learn how to copy files and folders using cp.
Command Name: cp(copy)Function Description: copy one file to another, or copy several files to another directory.
Syntax format:
　　 cp [options] source dest
cp [options] source... directory Common parameters:
　 -A tries its best to copy the file status, permissions, and other information as they are.
-R if the source contains the directory name, the files under the directory are also copied to the destination in sequence.
-F if the destination already has an archive with the same file name, delete it before copying.Command instance:
1. copy the file aaa (already exists) and name it bbb:
　　 cp aaa bbb 2. Copy all C language programs to the Finished subdirectory:
　　 cp *.c Finished3. copy the file in the specified directory to the current directory and rename it. [root@rehat root]# cp ~/.bashrc bashrc_bak4. Force copy the file from the specified directory to the current directory, regardless of whether the current directory contains the file [root@rehat root]# cp -f ~/.bashrc bashrc5. Copy the specified directory to the current directory. [root@rehat root]# cp -r /root/test .
[root@rehat root]# cp -r /root/test/ .The two have the same effect. When copying a directory, all the last-level directories in the source path will be copied, including the directory itself.
6. copy the files in the specified directory to the specified directory. [root@rehat root]# cp ~/.bashrc /bak/.bashrc7. Copy all the attributes of the source file during replication. If no parameter is specified, the properties of the target file and the source file may be inconsistent. [root@rehat root]# cp -a ~/.bashrc /bak/.bashrc8. If the two folders need to be synchronized, one file is changed, and the other file is changed, but ensure that the files of the two files are the latest. [root@rehat root]# cp -u /src/.bashrc /bak_src/bashrc9. Copy all files in the specified directory to the current directory. [root@rehat root]# cp -r /root/test/* .
