Usage of CP commands in Linux

CP Replication

CP source file path Directory file path
[Root@zabbix_agentd ~]# CP./1.sh/tmp/
[Root@zabbix_agentd ~]# CP./1.sh/tmp/2.sh

As shown above, the first CP./1.sh/tmp/, copy the current directory under 1.SH to TMP is still called 1.sh,
Second CP./1.sh/tmp/2.sh, copy the current directory under 1.sh to rename to 2.sh under TMP

If the directory file exists, you are prompted to overwrite it
Create a new file if the destination file does not exist
If the directory exists and is a directory: Copy to the target directory and keep the original

Of course, the source file can also appear multiple, if the source is multiple, the target must be a directory
[Root@zabbix_agentd ~]# cp 1.sh 1.txt anaconda-ks.cfg/tmp/
Cp:overwrite '/tmp/1.sh '? Y
[Root@zabbix_agentd ~]#

CP Replication Directory-r if the target file exists there will be an error
[Root@zabbix_agentd ~]# cp-r/etc/zabbix/tmp/zabbix123
[Root@zabbix_agentd ~]# ll/tmp/zabbix123
