Which command is used to copy files in UNIX?

Answer:

Explanation:

The cp command in UNIX is used to copy files and directories from one location to another. Its syntax is cp source destination, where source is the file to be copied and destination is the target directory or filename.

This command is useful for duplicating files or creating backups. For example, cp file1 file2 will create a copy of file1 and save it as file2. The -r option allows copying directories recursively, which includes all subdirectories and their contents.

Understanding the cp command is vital for managing files in UNIX. It allows users to keep multiple versions of files or easily transfer files between different directories without losing the original.
