How do you copy a file in Linux?

The cp command is specifically designed for copying files and directories in Linux. When using cp, you provide the source file path you wish to copy and the destination path where you want the new copy to be located. This command creates an exact duplicate of the original file, preserving the contents and attributes of the source file.

For example, if you had a file named "document.txt" and you wanted to create a copy of it in a directory called "backup," you would use the command cp document.txt backup/document.txt. This command would ensure the original file remains unchanged while placing a new copy in the specified directory.

The other choices involve commands that either move files, which does not create a copy, or are incorrect. The mv command is used for moving files rather than duplicating them. The copy command does not exist in Linux; instead, cp serves that purpose. Finally, the rm command is used to remove files and does not facilitate any form of file duplication.
