This article introduces the relevant knowledge of "the method of directly overwriting commands under cp under CentOS". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

When cp is overwritten, no matter what parameter-f is added or whether the prompt is overwritten or not, copy directly the files in the test directory to the test1 directory without packaging.

Cp-r test/* test1

When you execute the above command, every file that exists in test1 prompts you whether to overwrite

Cp-rf test/* test1

When you execute the above command, every file that test1 exists will no longer be prompted

This is the ideal state we want, but sometimes with-f added, there will be a hint.

Because the server will add the alias alias cp='cp-iTunes by default, when you execute cp, you actually execute cp-I.

You can see it under alias.

# alias

Alias cp='cp-i'

You can solve the problem with the following

# vi ~ / .bashrc

Add "#" before alias cp='cp-i' and comment out the line,: wq! Save and launch, and then log in again.

Next time you use cp-rf, you can directly overwrite the existing files.

Of course, if you don't want to change the alias, you can escape it,\ cp-rf.
