![]() Let’s take a look: get_xattr_raw("~/Downloads/RStudio-1.2.627.dmg", ":kMDItemWhereFroms") This is the key Apple has standardized on to store the source URL of a downloaded item. ![]() There are four keys we can poke at, but the one that will help transition us to a larger example is :kMDItemWhereFroms. Library(tidyverse) # we'll need this later Library(reticulate) # not 100% necessary but you'll see why later We’re not going to work with the entire package in this post (it’s really straightforward to use and has a README on the GitHub site along with extensive examples) but I’ll use one of the example files from the directory listing above to demonstrate a couple functions before we get to the main example.įirst, let’s see what is hidden with the RStudio disk image: library(xattrs) Let’s use the xattrs package to rebuild a list of download URLs from the extended attributes on the files located in ~/Downloads (if you’ve chosen a different default for your browsers, use that directory). We grab papers, data, programs (etc.) and some of those actions are performed in browsers. Exploring Past Downloadsĭata scientists are (generally) inquisitive folk and tend to accumulate things. You can work with extended attributes from the terminal with the xattr command, but do you really want to go to the terminal every time you want to examine these secret settings (now that you know your OS is keeping secrets from you)? When you’re in a terminal session you can tell that a file has extended attributes by looking for an sign near the permissions column: $ cd ~/Downloads ![]() Apart from that, you can put anything in the value: text, binary content, etc. ![]() They key must be a character value & unique, and it’s fairly standard practice to keep the value component under 4K.

These attributes can serve useful purposes. One of these ways is by associating extended file attributes with files.
