Question

Please provide screenshots for the following so, I may see how the commands work thank you.

• Create a new folder called "SharedEngrSales". Configure it so that users from the engr-sales group can share documents for both read and write among themselves
• Start the following long-running process: "tree / > tree.out". Quickly, before it finishes, pause the process and put it in the background. Type a command (perhaps "ls") and then bring the background process to the foreground
• Start another long-running process (same as above). Pause the process and then kill it
• Display the list of environmental variables (without showing aliases and functions)
• Display a list of systemd services that are currently configured
