Renaming the files and directories is a frequent task .Fortunately, Linux has an effortless way of renaming files and directories.
The mv command is basically used to move the files from one location to the another.But it’s also widely used as a way to rename files as well.
mv [old_name_of_directory] [new_name_of_directory]
First, check the directories present in the current working directory .
Now, we will rename the folder named daa to robot .
mv daa robot
Then, check the list of directories again .
gaurav@ubuntu:~/workspace$ ls dmta pc pmcd qps robot ssda
If you try to change a directory to a name already used by another directory in the desired location, the old name will be deleted and written with the new one.
gaurav@buntu:~/workspace$ mv dmta qps gaurav@ubuntu:~/workspace$ ls pc pmcd qps robot ssda gaurav@ubuntu:~/workspace$
Using rename Command To Rename Directories
Mv is a very basic command and also has ambiguous behaviour.To overcome these shortcomings we can use the rename command.
Install rename on Ubuntu and Debian :
sudo apt-get install rename
After installing rename, use the code below rename a directory.
sudo rename [perl expression] [directory]
root@ubuntu:~# ls DIR1 dir2 dir3 dir4 dir5 pc snap
root@ubuntu:~# rename 's/dir2/ssh/' dir2 root@ubuntu:~# ls -l total 28 drwxr-xr-x 2 root root 4096 Sep 9 15:15 DIR1 drwxr-xr-x 2 root root 4096 Sep 9 15:15 dir3 drwxr-xr-x 2 root root 4096 Sep 9 15:15 dir4 drwxr-xr-x 2 root root 4096 Sep 9 15:15 dir5 drwxr-xr-x 2 root root 4096 Sep 9 15:19 pc drwxr-xr-x 3 root root 4096 Sep 9 14:59 snap drwxr-xr-x 2 root root 4096 Sep 9 15:15 ssh
Rename Multiple Directories at Once Using rename Command

sudo rename 'y/a-z/A-Z/' [directories_to_rename]
Using renaming to change the names of the highlighted directory.
