+# 🦬 pdubs
+pdubs is a simple command-line utility to return macos window information for a given pid. If a given pid does not have an associated window, then it will check all of its ancestors. The window information for the first pid that is associated will be returned. The window information is a list in JSON format.
+
+You may supply one optional parameter providing the pid. If no parameter is provided, then it will search for the current processes pid.
+
+## 🤔 Motivation
+I wanted an easy way to get the window ID of my current process so that I could take a screenshot from the command-line with [screencapture](https://ss64.com/osx/screencapture.html).  
+### screenshot example
+```bash
+win=$(./pdubs | jq .[0].kCGWindowNumber); screencapture -l"$win" pdubs.png
+```
+![pdubs](https://github.com/mikesmithgh/pdubs/assets/10135646/5e389586-717a-4f60-9f59-30a40eea1548)
+
+## 📦 Installation
+
+### Download the binary for your system
+```sh
+curl --silent --fail --location --output pdubs.tar.gz https://github.com/mikesmithgh/pdubs/releases/latest/download/pdubs.tar.gz
+curl --silent --fail --location --output pdubs.tar.gz.sha256 https://github.com/mikesmithgh/pdubs/releases/latest/download/pdubs.tar.gz.sha256
+if shasum -c pdubs.tar.gz.sha256; then 
+  tar -xvf pdubs.tar.gz 
+else
+  rm pdubs.tar.gz
+fi
+```
+Move the binary `pdubs` to the desired location and place on your `$PATH`
+
+For example,
+```sh
+mv pdubs ~/bin
+```

+
+## 🕵️ Troubleshooting
+
+### Developer cannot be verified warning
+```
+"pdubs" cannot be opened because the developer cannot be verified.
+```
+If you receive the warning message while trying to execute pdubs, this is most likely because you manually downloaded the file from the release page. Depending on your download method, Apple will quarantine an app if it is not by an identified developer. I do not have an Apple developer account which is why you will see this warning.
+
+Before removing the app from quarantine, please verify the checksum has not been changed with the `shasum` command. If this fails, then delete and download pdubs from the release page.
+```sh
+shasum -c pdubs.tar.gz.sha256
+```
+
+You can manually resolves the quarantine by control-clicking and opening the application from Finder or via the following command.
+```sh
+xattr -d com.apple.quarantine pdubs
+```
+See [What should I do about com.apple.quarantine?](https://superuser.com/questions/28384/what-should-i-do-about-com-apple-quarantine) for additional information.
