RM command usage in Linux

MV Mobile, similar to Windows Mobility, similar in usage and CP
You can move directories directly without the-r option;

MV/1/2.TXT/1/3 the name of 2.txt under directory 1 to 3
mv/1/2.txt/3/move 2.txt under directory 1 to directory/3/
If the directory is the same, renamed, if the directory is not the same move, if the directory is different and the name is different also for renaming, such as: MV 2.txt/tmp/3.txt

RM Delete files, remove files

[Root@zabbix_agentd ~]# Rm/tmp/3.txt
Rm:remove regular empty file '/tmp/3.txt '? Y
[Root@zabbix_agentd ~]#

Delete Directory

If there is a file in the directory, it will not be deleted, except by adding-R, recursively deleting all files in the directory

[Root@zabbix_agentd ~]# mkdir file && Touch file/1.txt
[Root@zabbix_agentd ~]# RM file/
Rm:cannot remove ' file/': is a directory
[Root@zabbix_agentd ~]# rmdir file/
rmdir:failed to remove ' file/': Directory not empty
[Root@zabbix_agentd ~]#

-R Recursive Delete, do not use alias-I, do not prompt to delete
[Root@zabbix_agentd ~]# \rm-r file/

RM-RF/Can be performed before Red Hat 6, after which you will need to add--no-preserve-root, do not protect stub, this operation would remove the system

[Root@zabbix_agentd ~]# RM-RF/
Rm:it is dangerous to operate recursively on '/'
Rm:use--no-preserve-root to override this failsafe

If RM-RF/* Deletes the file under the root, not the root
