Brace expansion lets you generate arbitrary strings in your terminal. Place a comma-separated list of items in curly braces {} and add prefix and/or suffix. It will repeat the prefix / suffix for every item in the list.

# Deletes image-01.png, image-17.png and image-42.png

$ echo "Hello "{World,everyone}
Hello World Hello Everyone
