I needed to move a bunch of files from an old blog to the new one for conversion. Here’s how:

find . -name \*.asciidoc -exec cp {} /home/sionwilliams_com/site/content/post  \;

From the current directory it searched for files ending .asciidoc and moved them to the new location.

Once in the new location I was able to change the extension of the files with:

for f in *.asciidoc; do mv -- "$f" "${f%.asciidoc}.md"; done
