The mv command can be used to:
Move a file
In this example, /home/john.doe/foo.txt is moved to the /tmp directory.
mv /home/john.doe/foo.txt /tmp
Or, this would have the same result.
mv /home/john.doe/foo.txt /tmp/foo.txt
Rename a file
The mv command followed by the current file name and then a new file name can be used to create a new file with a different name. In this example, foo.txt is moved and renamed to bar.txt. This can be dangerous. If bar.txt already exists, bar.txt will be overwritten with no prompt or warning.
mv foo.txt bar.txt
The -i or --interactive option can be used to display an interactive prompt. The interactive prompt can prevent a file from being overwritten. In this example, a file named foo.txt already exists in both the /home/john.doe and /tmp directories. When attempting to move file1 from /home/john.doe to /tmp, a prompt appears.
mv -i /home/john.doe/foo.txt /tmp mv: overwrite '/tmp/foo.txt'?
Last modified date and time
Moving a file will not update the last modified date and time of the file. On the other hand, the cp (copy) command is used, the last modified date and time of the new file will be the current date time.
