How can you renaming a file in Linux?

Renaming a file in Linux is achieved using the mv command. This command is primarily known for moving files and directories, but it also serves the dual purpose of renaming them. When you use mv, you specify the current name of the file followed by the new name you want to assign it. For example, if you have a file called oldname.txt and you want to rename it to newname.txt, you would use the command mv oldname.txt newname.txt. This effectively changes the name of the file without creating a copy; it simply updates the reference to that file within the filesystem.

The other options do not function as standard file renaming commands in Linux. The rename command is a script that allows more advanced renaming features based on regular expressions but is not as commonly used for simple renaming tasks. mvfile is not a standard command in Linux, and mod does not relate to file renaming. Therefore, using mv is the most straightforward and effective way to rename a file.
