How to change sort order of text?

Question

Text Processing Automation

There is a large chronology of textual data, but initially I began to write in the order “old data on top, new data on the bottom”. Now you need to change the order, and write new data on top, and leave the old data at the bottom. Maybe there are some tools to change the order of the text?

example now so
13 03 110 72 71 three
13 04 118 74 66 zero 13 10 117
75 69 six
14 08 132 88

73
four
five
69 six
13 04 118 74 66 zero
13 03 110 72 71 three

Answer 1

tail -r <ваш файл> > <новый файл>

Answer 2

tac исходный_файл > новый_файл
Writes data in reverse order to new_file .
