cmd = string[/\s(\S+)$/, 1]
doesnt fetch me anything:)

program=string.split.last
what if
string = "root     14051 14033  3 08:39 pts/2    00:00:00 /bin/bash -x 
-s"
it fetches only -s for me.
sec, last =  string.split.values_at(1, -1)
doesnt work for the same reason
i need everything after 00.00.00 till the end
i.e., /bin/bash -x -s

program=string[/[a-z\/]+$/]
the command column mauy start with character. i dont want to limit it in 
my regexp. it has to be generic.

with all your comments, i tried
      pid = run_process[/\s(\d+)/, 1]
      cmd = run_process[/:\d+:\d+\s(\S.*)\s$/, 1]

is there any other way?
