Hello, everybody. I understand that there are many similar topics, but since I am a foreigner(Ukrainian) and do not understand English, even with a translator, I have problems anyway. Do not be indifferent, please help! So, I use this code start.sh - https://github.com/Crysalix/PixelStart.sh/blob/master/start.sh. Server operating system - Debian 10.1. For example, when I enter a command ./start check, then I get a grep error: View attachment 480227 Or, when I enter a command ./start start: View attachment 480228 And here errors grep What should I do? Please, tell me! Thanks in advance!
