Rename multiple files from a list

Problem:

I have to rename multiple files, I have the list with filenames and I can specificy the new filename into a list (csv file).

Solution:

Create your csv file, save as listado.csv. The first column contains the original filename, the second column contains the NEW filename. Example:
```
uno.txt,1.txt
dos.txt,2.txt
tres.txt,3.txt
```
Note: You don’t need to type (write) the filenames in the first columns. You can get them using this command:
```
ls *.txt > listado.csv
```
Then you can open and edit listado.csv to add the new filenames in the second column (don’t forget type comma).
Create a bash script. Save it as: rename-all-list.sh.

#!/bin/bash
##Rogelio Prieto, February 2021.
list_filename='listado.csv'
n=1
while read line; do
#reading each line

filename=$(echo $line | cut -d"," -f 1)
newfilename=$(echo $line | cut -d"," -f 2)

echo "Archivo No. $n : $filename"
echo "Nuevo nombre: $newfilename"
echo "======================"
mv $filename $newfilename

n=$((n+1))
done < $list_filename

Execute the rename-all-list.shscript:

chmod +x rename-all-list.sh
./rename-all-list.sh
