Hi All,

I put the following message on ruby-talk@ruby-lang.org

malug is discussing the following question:

How to print the rightmost word for every line in <FILE>?

I tried to introduce ruby to the debate. But am not sure I have the best

solution.

ruby -ne 'arr=split; puts "#{arr.last}"' <FILE>  #john

I less than three hours, I got the following replies:

ruby -ne "arr=split; puts arr.last" [file] #Tobi
ruby -nae 'puts $F[-1]' <FILE>

You'll get nils in the output for blank lines; depending on what you
want to

ruby -nae 'puts $F[-1] if $F[-1]' <FILE>

ruby -lane 'puts $F[-1] || ""' <FILE>        # Dossy

Much though I like Ruby, I use "awk '{print $NF'}" for that.  Clifford
Heath

ruby -lane 'print $F[-1]' <FILE>  # matz < matz is the creator of ruby.>

ruby -ne 'puts split.last' <FILE>
ruby -nae 'puts $F.last' <FILE> #But it prints 'nil' for empty
lines.Mike Hall

All this --  including a response from matz.

We are in a real learning community. :)

My favorite because it is object oriented
is:                                     ruby -ne 'puts split.last'
<FILE>

matz's version will appeal to awk or perl affectionadoes:
ruby -lane 'print $F[-1]' <FILE>
