What command is used to copy files in Linux?

The command used to copy files in Linux is "cp". This command is specifically designed for copying files and directories, allowing users to create duplicates of their data in different locations within the file system. The basic syntax for the command includes specifying the source file and the destination where the copy should be placed.

For example, using the command cp file1.txt file2.txt will create a copy of file1.txt and save it as file2.txt. The command also offers various options to modify its functionality, such as copying recursively with the -r flag for directories or using -i to prompt before overwriting existing files. Understanding the "cp" command is fundamental for file management in Linux, making it an essential tool for both new and experienced users.
