This article mainly introduces "what are the parameters of the Linux cp command". In the daily operation, I believe many people have doubts about the parameters of the Linux cp command. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubts about "what are the parameters of the Linux cp command?" Next, please follow the editor to study!

Cp (copy file or directory)

[root@linux ~] # cp [- adfilprsu] Source file (source) destination file (destination) [root@linux ~] # cp [options] source1 source2 source3 … . Directory

Parameters:

-a: equivalent to-pdr

-d: if the source file is a linked file attribute (link file), copy the linked file attribute instead of the file itself

-f: for the meaning of force, if there is any repetition or other doubt, the user will not be asked, but the copy will be forced.

-I: if the target file (destination) already exists, it will first ask if it is a real action when overwriting!

-l: link file creation for hard link instead of copying the file itself

-p: copy it along with the properties of the file instead of using the default properties

-r: recursive continuous replication for directory replication behavior

-s: copy into a symbolic link file (symbolic link), that is, a "shortcut" file

-u: update destination only if destination is older than source!

Finally, it should be noted that if there are more than two source files, the last destination file must be a "directory"!

Do not prompt for override information overwrite?

\ cp-r-f source target

Does the cp command not prompt overwrite by default? Yes, but the-I option of cp will prompt, while the general linux startup file ~ / .bashrc will name cp as

Alias cp='cp-i'

So typing the cp command under linux actually runs cp-I, plus a "\" symbol to make this cp command run without an alias (cp-I).

At this point, the study of "what are the parameters of the Linux cp command" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
