what does Get-Process do without options?
give you process information for each running process in the system, or on a remote computer.
how would you display the top processes in powershell using the most cpu?
Get-Process | Sort CPU -descending | Select -first 3 -Property ID,ProcessName,CPU
what does the command
Sort CPU -descending
do?
feeds piped input into the sort command, which sorts the input based on the CPU column, in descending order from least to greatest.
the Get-Process command is singular in its name, but can it get many processes?
yes.
computer idea:
the ergolap: a computer or computer-holding or adapting device that is as portable as a laptop, but allows you to move the screen to be eye-level height, and to use a keyboard that can be pulled out and ergonomically manipulated from by the screen.
ideally, the device would be able to be molded to fit multiple shapes and still allow rapid keypad entries.
I wonder if this is being made or has been.
what does the
Format-List *
cmdlet do?
displays all available properties * of the piped input.
How many mb is requested for the command
Where-Object {$_.WorkingSet -gt 20000000}
20

what is the Google DNS IP address?
8.8.8.8
what should you set for the DNS server addresses?
208.67.222.222

those are opendns, and you can also use
8.8.8.8
and
8.8.4.4
which belong to Google

how do you get out of the top command?
q
what is one of the most common reasons for a user’s computer to be running slow?

LSOF command
what is a use case for the LSOF command?
troubleshooting the:
