On RHEL it’s simply sudo dnf update -y

I missed where the person you replied to said to never use the terminal again, now your comment makes perfect sense. I thought you were conflating the preference for powershell with windows and therefor more GUI.

My bad, and I completely agree with you, if I had to give up CLI or GUI it would be GUI hands down no competition at all, I would die without CLI.

$time = (get-date).adddays(-30)
gci -file -filter *.pdf `
  | ? { $_.lastwritetime -gt $time } `
  | % { convert -density 300 $_.fullname $($_.fullname + ".jpg") }
