Info

The basic idea is to count all the lines that end with /. Here we can see we have only one directory.Pipes are a great option to find and kill processes. Say we want to find the process ID of nautilus,and kill all running instances. For this we use:ps aux | grep nautilus | grep -v grep | awk '{print $2}' | xargs kill
ps aux: This prints all processes with PID| grep nautilus: Find the ones matching nautilus| grep -v grep: Inverts grep to exclude the grep process| awk '{print $2}': Selects the second word in the line, which is the PID| xargs kill: Here xargs is used to distribute each PID to a kill command. It is especiallyused for commands that do not read arguments from standard input.Now we've killed nautilus. This was purely a demonstrative example. There are other ways ofdoing this.Let's open nautilus again and send it to the background by hitting Ctrl + Z followed by the bgcommand.Now let's run the following command:pgrep nautilusTo see all the pids of nautilus and to send the kill signal to all those processes, use the followingcommand line:pkill nautilusNow it's time for some networking! You probably know the ifconfig command, which is used toprint information about the network interfaces. To get the IP address of a specific interface (in our
