You did not read carefully the URL http://root.cern.ch/root/EnvVars.html
Unix commands are case sensitive and you must respect the syntax.
Assuming that you have installed root in directory myrootdir, do

setenv ROOTSYS myrootdir
set path=($path $ROOTSYS/bin)
setenv LD_LIBRARY_PATH $LD_LIBRARY_PATH:$ROOTSYS/lib

This must work in you use csh or equivalent shells.
It is convenient to add these 3 lines to your shell startup script.
