Two Ways To Print Lines From File Reversely

Ever tried to print lines in files in the reverse order? You will know two simple methods to print lines from file in the reverse order.

Imagine a file somefile.txt with content something like this:
a
b
c
d
e


Method 1:


$ tac somefile.txt
e
d
c
b
a


Method 2:


$ sort -r somefile.txt
e
d
c
b
a


You can achieve the same effect through other techniques as well but I'll stick to these simple ones :)
