Which command is used to copy files in Linux?

The command used to copy files in Linux is "cp." This command stands for "copy" and is one of the essential commands in Unix-like operating systems for duplicating files and directories. When you invoke the cp command, you specify the source file and the destination where you want the copy to be placed.

For instance, the syntax typically looks like this: cp source_file destination_file. There are also various options available with the cp command, such as -r for copying directories recursively or -i for interactive mode, which prompts before overwriting existing files.

The other options listed do not serve the purpose of copying files in Linux. "mv" is used for moving files or renaming them, while "copy" and "duplicate" are not valid commands in Linux for this operation. Understanding the correct command to copy files is crucial for managing files effectively in a Linux environment.
