| -f | Force move by overwriting existing files without prompting. |
| -n | No-clobber; prevents overwriting existing files. |
| -u | Update; move only when the source file is newer than the destination file or when the destination file is missing. |
| -v | Verbose mode; explains what is being done. |
| --backup | Creates backups of existing files before moving. |

Examples of mv Command in Linux
Here are some practical use cases to demonstrate how to use the mv command on your system −
- Moving a File
- Changing the Name of a File
- Forcibly Moving Files and Overwriting Existing Ones
- Consolidating Multiple Files into a Directory
- Enabling Detailed Output for File Moves
- Moving a Directory
- Renaming a Directory
- Using No-Overwrite Mode
Moving a File
To move a file from one location to another, use the following command −
mv /path/to/source/file.txt /path/to/destination/
This command moves file.txt from its current directory to the specified destination directory.
Changing the Name of a File
If you need to rename a file within the same folder, employ the following command −
mv oldname.txt newname.txt
This command changes the file's name from oldname.txt to newname.txt. This is particularly useful for correcting naming errors or implementing a new naming convention.
Forcibly Moving Files and Overwriting Existing Ones
To move a file and ensure that any existing file with the same name in the target location is overwritten, use the -f option −
mv -f /path/to/source/file.txt /path/to/destination/
With the -f (force) option, this command moves file.txt to the target directory, replacing any file that already exists there. This is useful in automated scripts where you want to suppress any prompts.
Consolidating Multiple Files into a Directory
To move several files into a single directory, list all the source files followed by the destination directory −
mv file1.txt file2.txt /path/to/destination/
This command transfers file1.txt and file2.txt to the target directory. It's handy for consolidating related files into a common directory.
Enabling Detailed Output for File Moves
For a verbose output that details each step of the file moving process, use the -v option −
mv -v file.txt /path/to/destination/
This command provides a detailed output of the move operation, including the source and destination paths. This is helpful for monitoring and verifying the actions being taken during the move.
Moving a Directory
To move an entire directory and its contents to a new location, you can use the following command −
mv /path/to/source/directory /path/to/destination/
This command relocates the directory from its original path to the specified destination. It's a straightforward method to reorganize your directory structure.
Renaming a Directory
If you need to rename a directory without changing its location, use this command −
mv old_directory new_directory
This command changes the name of old_directory to new_directory. This is useful for updating directory names to better reflect their contents.
Using No-Overwrite Mode
To move a file without overwriting an existing file at the destination, utilize the -n option −
mv -n /path/to/source/file.txt /path/to/destination/
The -n (no-clobber) option ensures that file.txt is only moved if there is no existing file with the same name in the destination directory. This helps prevent accidental data loss.
Conclusion
The Linux mv command is an indispensable tool for managing files and directories in Unix-like operating systems. Its flexibility and range of options make it suitable for various tasks, from simple renaming to complex file organization. Mastering the mv command can significantly enhance your efficiency in handling your file system.
