echo `echo \`date\`` - due to the back ticks, the shell will complete the `date` portion, then echo it back to you (a waste of processor since date automatically puts it to standard out.


echo `echo date` - yes, it does print the word date since that is what you told it to do - echo date - not echo the output of the command date. You could set up a variable such as today to show it.
today="date"
echo $today
today=`date`
echo $today
