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 a fundamental utility in the Linux operating system. When you use "cp," you can specify the source file(s) and the destination where you want to copy them. This command allows various options, such as recursive copying of directories, preserving file attributes, and prompting before overwriting existing files.

For example, if you wanted to copy a file named "file1.txt" to another file called "file2.txt," you would use the command like this: cp file1.txt file2.txt. This action would create a copy of "file1.txt" and name it "file2.txt" in the current directory, while retaining the contents of the original file.

Other options mentioned do not fulfill the function of copying files in Linux. The "mv" command is used to move files or rename them rather than create copies. "copy" is not a valid command in the Linux environment; it's used in some other operating systems like Windows. "duplicate" is also not a recognized Linux command for copying files. Hence, "cp" is the appropriate choice for this function.
