All my friend have shared their thoughts about the most important command. But in my opinion
echo
is the best

Because you do not stick with the command line if you love CLI. Soon you will enter in the world of Shell scripting, which is also the composition of linux commands and echo is the command that will let you know where you are going with your script, till your scrit will become a program.
In linux mostly using command is network configaration command nmcli,ifconfig
and normally i used usermanagement commands like acl,chmod,chown,chgrp
becuase in linux we are not giving the all permissions to one file we restrict some people and some accounts on files so i use these commands alot
