Which command is used to move or rename files in Linux?

The command used to move or rename files in Linux is "mv". This command is fundamental in file management within the Linux environment. When you use the "mv" command, you can specify the source file that you want to move or rename and the destination path or the new name you want to give it.

For example, using "mv file1.txt /home/user/documents/" would move 'file1.txt' to the 'documents' directory. Alternatively, if you want to rename a file, you could use "mv oldname.txt newname.txt" to change the name of the file from 'oldname.txt' to 'newname.txt'.

This versatility allows for effective organization of files, making "mv" an essential command for users managing their file systems in Linux.
