Question

I need to write a script that will automatically rename a number of files and include a user defined string. As an example, I want the file *001.jpg renamed to "user defined string" + 001.jpg (ex: MyVacation20110725_001.jpg).

This is what I’ve tried so far:

#!/bin/sh

echo "Type the user-defined string, followed by [Enter]: "
read str
for file in *.jpg; do 
`sed s/$str_$file/$file/`;
done

The problem is that nothing is happening.

Answer 1

You can try this on your loop:

for file in *.jpg
do
mv ${file} $file$str
done
