How to rename files and directories in Linux


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

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.

root@ubuntu:~# ls

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
