Linux file copy FAQ: How do I copy Linux files and directories? (Or, Can you share some cp command examples?)
You use the Linux cp command to copy Linux files and directories. Let's look at some copy examples to see how this works.
At its most basic, here's how you copy a Linux file:
cp Chapter1 Chapter1.bak
This cp command copies the original file named Chapter1 to the new file named Chapter1.bak. After issuing this command both your original file and the new file will be in the current directory.
It's also easy to copy a Linux file to a different directory. Here's how you copy the same file to the /tmp directory:
cp Chapter1 /tmp
and here's how you copy a file one level up in the directory hierarchy:
cp Chapter1 ..
As a final note about copying files, you can also copy multiple files at one time, like this:
cp file1 file2 file3 /tmp
That command copies those three files to the /tmp directory.
You can also copy directories with the Linux cp command, and when you do this, you just need to remember to use the -r option. For example, this command copies the directory named Foo to the /tmp directory:
cp -r Foo /tmp
If you try to copy a directory without using the -r argument you'll get an error like this:
$ cp Foo /tmp cp: Foo is a directory (not copied).
so it's not too hard to remember to use that option.
I hope these Linux cp commands examples have been helpful. If you have any questions, or other uses of the copy command, just leave a note in the Comments section below.
