Using the SED stream editor in macOS terminal.app

This is pretty useful, piping the results of the echo to the “sed” command which stands for “stream editor” and then iterating over things in a loop and batch renaming them. I could have renamed them manually, but this was more fun and I learned something!

for x in *\ *; do y=$(echo "$x" | sed y/\ \/./); mv "$x" "$y"; done
