I want to rename all files called Caudate_masks to lower case: caudate_masks.

In my directory I have several folders, one of them called Controls and other one called Patients. Inside each one of them you can find the Caudate_masks folders.

   Controls



   └───C01

   │   └─── Caudate_masks

   │   └─── ...     

   └───C02

   │   └─── Caudate_masks

   │   └─── ...

   └───C03

   │   └─── Caudate_masks

   │   └─── ...





   Patients



   └───H01

   │   └─── Caudate_masks

   │   └─── ...

This is what I have:

#!/bin/bash

DIR="/media/roy/Analysis"

for group in Controls Patients; do

    cd $DIR/$group || exit

    for folder in *; do

        for cortical in "$folder/"*; do

            if [ $cortical = "$folder/Caudate_masks" ]; then

                mv $cortical caudate_masks

            fi

        done;

    done;

done;

If I execute:

if [ $cortical = "$folder/Caudate_masks" ]; then

                echo $cortical

I get a list of all the folders of interest, however, mv $cortical caudate_masks doesn´t change names, but move files, and rename doesn´t appear as a valid function.

Install the rename package:

sudo apt install rename

Then it's a shell one-liner:

[sh @ balrog] ~/tmp 27 % tree

.

├── a

│   └── Caudate_masks

├── b

│   └── Caudate_masks

└── c

    └── Caudate_masks



6 directories, 0 files



[sh @ balrog] ~/tmp 28 % rename 's/Caudate_masks/caudate_masks/' **/Caudate_masks



[sh @ balrog] ~/tmp 29 % tree

.

├── a

│   └── caudate_masks

├── b

│   └── caudate_masks

└── c

    └── caudate_masks



6 directories, 0 files

Notice that modern shells (bash, zsh) support the ** wildcard which means "somewhere in this directory tree".

The reason why your script doesn't work as expected is that in this snippet

        for cortical in "$folder/"*; do

            if [ $cortical = "$folder/Caudate_masks" ]; then

                mv $cortical caudate_masks

            fi

        done;

your old name contains the directory (from $folder), yet the new name does not. It should work if you change that line to

                mv $cortical $folder/caudate_masks
