What is the purpose of the 'mv' command in Linux?

• A. Delete a file
• B. Move or rename a file
• C. Copy a file
• D. Create a directory

Answer: (B)

The 'mv' command in Linux is primarily used to move or rename files and directories. When you use 'mv', you can specify the source file or directory that you want to move and the destination location where you want it to go. If the destination has a different name, the command will effectively rename the source file or directory to that new name.

For example, using 'mv file1.txt /home/user/documents/' transfers 'file1.txt' to the specified directory. If you were to use 'mv file1.txt file2.txt', it would rename 'file1.txt' to 'file2.txt' within the same directory. This dual functionality makes 'mv' a versatile tool in file management within the Linux operating system.
