Question

I need something which reverts words in a sentence in opposite order. I am sure it is possible to do without writing a script.

Something which receives an input stream like echo AAaa BBbb CCcc | foo and prints CCcc BBbb AAaa

Sorry, I changed the example, the words themselves should not be reverted. So, rev does not work

Answer 1

well when I saw this question, I thought tac or rev too. however I guess OP made a bad example with AAA BBB. he may want to revert “word”s but not all characters.

see this, if it is what you want:

kent$  echo "this is another test example"|awk '{for(i=NF;i>0;i--)printf $i" "}'
example test another is this
