Another is that it is possible to compress the data as it’s being copied.

How do I copy the same file in Linux?

The Linux cp command is used for copying files and directories to another location. To copy a file, specify “cp” followed by the name of a file to copy. Then, state the location at which the new file should appear. The new file does not need to have the same name as the one you are copying.

Does cp remove original file?
