Extract tar balls

[Bob Bernstein <poobah%ruptured-duck.com@localhost>]

I'm trying to follow _The NetBSD Guide_, but I am stymied by 
these instructions, at 
https://netbsd.org/docs/guide/en/chap-fetch.html

$ for file in *.tgz
> do
> tar -xzf $file -C /
> done

Entering that first line and pressing <Enter> just yields

"for: Command not found."

Are those steps, as printed, dependent on the use of a certain 
shell? I like tcsh.

When there are rational grounds for an opinion, 
people are content to set them forth and wait 
for them to operate. In such cases, people do 
not hold their opinions with passion; they hold 
them calmly, and set forth their reasons 
quietly. The opinions that are held with 
passion are always those for which no good 
ground exists; indeed the passion is the 
measure of the holder's lack of rational 
conviction.
