Question

Write a shell script to rename a file.

Answer 1

I am trying to write a script that takes a directory as a command line parameter and iterates over the files in the directory changing their extension to .bu .

I thought this would work but I'm getting the output '.bu' is not a target directory

#!/bin/bash

for f in $1; do
mv "$f".* .bu
done

Answer 2

Answer:

#!/bin/bash

#Renaming all files from .jpg file to .jpeg file format

for file in *.jpg

do

       mv "$file" "${file%.jpg}.jpeg"

done

Explanation

It searches for .jpg in the directory, if there is any file then it renames the .jpg file to .jpeg.
