Usually, you'll read values into an array + then walk the array in reverse. provides a great example of walking an array in reverse.

How about using the tac command (it does the opposite of cat), it copies files from end to start
$ for i in ( 1 2 3 4 ) ; do echo $i ; done >t.t1
$ cat t.t1
$ tac t.t1
$ for i in (5 6 7 8) ; do echo $i ; done | tac 

Open in new window


for i in $( tac The.File.You.Want.End.To.Start )

Open in new window

Or reversing some output:

produce_some_output | tac | do_something_with_end_to_start

Open in new window
