This is a short beginners guide on how to rename a file using the Linux command line.
The mv command.
To rename a file on Linux, you need to use the “mv” command. “mv” stands for move, which is what you are essentially doing when you decided to rename a file.
Let’s say for example that you want to rename a file called “error.log” as “error.log.old”:
mv error.log error.log.old
The command above will move error.log to error.log.old.
The interactive option.
As an added safeguard against accidentally overwriting existing files, you can use the “-i” option. This “interactive” option will ask you if want to overwrite any existing files, regardless of what permissions they have:
mv -i error.log error.log.old
If “error.log.old” already exists, you will be asked if you want to overwrite it or not. This may help to prevent a situation where you overwrite a file that you do not want to overwrite.
Using full paths.
Finally, here is an example of the mv command being used with full paths:
mv -i /var/log/error.log /var/log/error.log.old
