editing multiple files

Editing 1000+ files is not fun. Here’s a script that cycles through certain files in a directory and performs a search and replace.

#!/bin/bash
for filename in 20*.md; do
  sed -i -e 's/author: Ulysses/author: ulysses/g' $filename
done

In this particular script, it looks for files starting with 20 with an extension of .md.

The script uses the sed command to perform search and replace.
