Sloth app
Came across this interesting MacOS app called Sloth today. To quote the website,
Sloth is essentially a friendly, exploratory GUI built on top of the lsof command line tool.
To install it, I ran the following command
brew install --cask sloth
The binary is not signed so MacOS refused to open it the first time around. I went to the Security settings and clicked on "Open anyway".
The app shows you a list of files, directories, devices, pipes, ip/unix sockets opened by running apps. It's really interesting to see all the IP sockets opened by running processes.
Definitely going to keep this around.
