To find out if Nitroshare is running in Linux Mint, open a terminal window and type the following command and then press Enter: "pgrep nitroshare."
If you see one or more numbers displayed, this means the application is already running. For example, if I start NitroShare and then run the command, I see:
- yourname@your-computer ~ $ pgrep nitroshare
If you see no numbers, Nitroshare isn't running.
