Linux: remove file extensions for multiple files

For example, A.txt B.txt, I want to rename then to A and B . 

How can I do it with shell script? Or other method ? Thanks.

Answer 1

I would use something like:

#!/bin/bash

for file in *.txt
do
    echo "$file" "$( echo $file | sed -e 's/\.txt//' )"
done

Of course replace the two above references of “.txt” to whatever file extension you are removing, or, preferably just use $1 (the first passed argument to the script).
