Linux Common commands: CP,MV,RM

CP (copy)

The CP command can copy files or directories, and can also create linked files.

[[email protected] ~]# CP [-ADFILPRSU] source file (source) destination file (destination) [[email protected] ~]# CP [Options] Source1 source2 s Ource3. Directory-r,-R,--recursive copy directories recursively-p same As--preserve=mode,ownership,timestam Ps-a,--archive same as-dr--preserve=all [can keep linked files], generally only root execution

To copy a file :

# CP a B C D # What does that mean? Source:a b C, destination:d, copy a b c to directory D

# cp/etc/a.txt/tmp/b

If B is a directory: Copy the a.txt to the B directory

If B is a file:

If B does not exist, copy the a.txt and rename it to B

If b exists, indicates whether to overwrite

To copy a directory :

# cp/etc/tmp

Cp:omitting directory '/etc '

# cp-r/etc/tmp # Copy directory needs to use the-r recursion option

To copy a hidden file :

With CP */tmp How can I copy the hidden files together in this type of operation?

We can only copy all non-hidden files by playing this command above. The reason for this is:(wildcard characters cannot match the file name with "." Files that begin with)

# cp-a. /tmp # Right

# CP. */tmp # just copy hidden files

MV (move)

The MV command is typically used to move files and rename them.

# mv/etc/somedir/tmp/somefile # error, cannot use directory to overwrite file

# mv/etc/somedir/tmp/somedir # Yes

RM (remove)

The RM command is used to delete files and directories. With it the basic will not use rmdir this again.
