Which command copies files?

Which command copies files?

• A. Cp
• B. Mv
• C. Mkdir
• D. Ls

Answer: (A)

Copying a file in a command-line environment is done with the command that duplicates the contents from a source to a new file at the destination. The standard tool for this in Unix-like systems is cp. For example, cp source.txt destination.txt creates a new file named destination.txt with the same data as source.txt. If you specify a directory as the destination, the file is copied into that directory with the same name. You can also copy multiple files at once by listing them and then giving a directory as the destination, or use wildcards like cp *.txt dir/ to copy all text files into a directory. When you need to copy whole directories, you add an option to do it recursively, such as copying all contents of a directory into another location. The other commands have different roles: moving or renaming uses mv, creating directories uses mkdir, and listing contents uses ls.
