Reversing text order of each line of a file in UNIX
My input is:
Code:
hello how are you
my chemistry book is lost
what is up
etc...

And I want the output to be:
Code:
you are how hello
lost is book chemistry my
up is what
....

I found an earlier response to a similar question but it was not accurate as it required a certain string length for each line
