hi,
I have to reverse the command output like below:
output:

disable
maintening
killed

How to reverse this output like:

killed
maintening

online

It should be ksh script.

Thanks very much!

Some systems have a command, tac, that does what you want. If not, you can do it with:

awk '{ x = $0 "\n" x } END { printf "%s", x }'

hi,
I have found a way to share, welcome more comments for it.

$ printf "%s\n" 1 2 3 4 | tail -r
tail: invalid option -- r
Try `tail --help' for more information.

tail -r temp
