How can I reverse the order of lines in a file?

I'd like to reverse the order of lines in a text file (or stdin), preserving the contents of each line.

So, i.e., starting with:

foo
bar
baz

I'd like to end up with 

baz
bar
foo

Is there a standard UNIX commandline utility for this?

Solution

  • BSD tail:

    tail -r myfile.txt
