##Run a command to see all the processes running on the server owned by everyone.

ps 

##Confirm the username you are running as.

echo $USER

##Run a command to see all the processes running on the server and use grep to select only the processes your user is running.

ps -ef | grep "root"

##Repeat the previous exercise. This time, select every process except things running as you.

ps -ef | grep "jeff"

##Show the process info for our current session without using a grep command.

ps -ef

##Show the process tree for the current session.

pstree

##Run a process check on the server but only output the User, pid and cmd columns to your results.

ps -eo pid,cmd,user

##Run a process check to pull all of the process ids running on the server and put the output into a file named list in your home directory.

ps > /Users/Jeff/practice_sre_training/list

##Run the following series of commands:

--sleep 300 &

--Find this command by checking the processes and running a grep
ps grep 27176

--Stop the process using the process id
sudo kill -9 27176

--Run a command to see a dynamic view of all the processes running on your host.
btop

##Now run the same command but specifically only for root.

ps grep "root"
sudo kill -9 xxxxx

##Experiment with the following commands while running top and note your observations:

z - nothing happens
c - mode[n]: appears
Shift P - nothing happens
k - nothing happens

##Run a command to check network connectivity between your Linux session and yahoo.com.

ping yahoo.com

##show the network route between your session and yahoo.com and output the contents into a file named yahoo.route in your home directory.

traceroute yahoo.com > yahoo.route /home

##View the file using less and see how many hops it took to get there.

cat less yahoo.route

##Create a soft link named route to your network route.

ln -s yahoo.route route

##Run a command to see all the network sockets on your server and output to a file named output in your home directory.

ifconfig > output /home

##Create a folder named network in your home directory.

mkdir network

##Move your route file and network output file into the network folder you just created.

mv /home/output /home/network | mv /home/route /home/network

##Run the command to query your network interfaces on your session.

netstat
