After all of these updates to my dotfiles, I finally want something that I can use to keep them up to date. For that, let’s write a quick script that can do just that.

Sometimes cat just prints too quickly.
Another random task that I find myself doing distressingly often: performing a regular expression search and replace recursively across a bunch of files. You can do this relatively directly with tools like sed, but I can never quite remember the particularly flavor of regular expression syntax sed uses.
A few new git aliases:
git undo - Undo the most recent commit, unstaging all new filesgit up - Update remote branches and submodules, delete merged branchesgit wipe - Remove all current changes, saving as a seperate branchQuite often when working with internet data, you will find yourself wanting to figure out what sort of device users are using to access your content. Luckily, if you’re using HTTP, there is a standard for that: The user-agent header.
Since I’m in exactly that position, I’ve added a new script to my Dotfiles that reads user agents on stdin, parses them, and writes them back out in a given format.
A fairly common set of command line tools (at least for me) is to combine sort and uniq to get a count of unique items in a list of unsorted data. Something like this:
$ find . -type 'f' | rev | cut -d "." -f "1" | rev | sort | uniq -c | sort -nr | head
