what is pb fr?

PB is a simple command line tool that lets you send push notifications and files through Pushbullet directly from your terminal. Instead of opening a browser or app to push a link, note, or file to your phone or other devices, you just type a quick command and it's done. The tool is built in Go and works as a lightweight bridge between your terminal and the Pushbullet service. Pushbullet is a service that connects your devices so you can share things between them, like sending a link from your computer to your phone so you can read it later on the go. This command line interface lets you trigger those pushes without leaving whatever you're working on in the terminal. The people who would get the most out of this are developers, system administrators, or anyone who spends a good chunk of their day in the terminal. For example, if you're running a long script and want a notification on your phone when it finishes, you could add a PB command at the end of your script. Or if you find an interesting link while working and want to send it to your phone for later reading, you can do it in a couple of keystrokes. It's really about saving the friction of context-switching away from your work. The README doesn't go into much detail beyond the basic description, so specifics about installation steps, supported command flags, or configuration aren't documented there. That said, the concept is straightforward enough, it's a no-frills utility designed to do one small job conveniently for people who live in the command line.
