Question

I want to rename all files in a folder and add a .xml extension. I am using Unix. How can I do that?

Answer 1

On the shell, you can do this:

for file in *; do
    if [ -f ${file} ]; then
        mv ${file} ${file}.xml
    fi
done

Edit

To do this recursively on all subdirectories, you should use find:

for file in $(find -type f); do
    mv ${file} ${file}.xml
done

On the other hand, if you’re going to do anything more complex than this, you probably shouldn’t use shell scripts.

Better still

Use the comment provided by Jonathan Leffler below:

find . -type f -exec mv {} {}.xml ';'
