Tools I made

On this page I list a bunch of (developer) tools I enjoy using in my work and elsewhere.

prex is to sed, what awk is grep.

Yes yes, I’m old now and sd and rg exist, but they didn’t back then!


A version of jq that I can understand.


Easily get a small overview of what changed between two folders.

UNIX’s diff -qr can also do this to some extent. Alternately, rsync --dry-run -c -r -v.
