@itsfoss just one are you kidding? um. sudo. head, tail, cat, grep, chmod, ifconfig, ping. Pipe if operators count.

@bluetea @itsfoss I haven't use 'head', 'tail', 'iconfig', 'ping' before, what do they do? I think 'ping' tests if there's internet or something like that?

@omarhossam50 @itsfoss head and tail look at the start or end of a file, very handy for quickly checking logs. Ping to test network response. ifconfig to see your network settings.
