I recently updated my site to make use of cover images on the post
listing. I wanted to make sure that I got all of the posts that need to
be updated. I used grep to find posts which had an image in them, but no
cover attribute in their front-matter.
I’ve been working on a fortran codebase with a lot of code duplicated
between subroutines, so I came up with this little bash function using
awk to extract subroutines, so I can find the difference between them.
