Try this.  Try using Control-r to search backward in history for your
command.  Then try using Control-o to Operate on the line and to get
the next line.

  $ echo one
  $ echo two
  $ echo three
  ... type in control-r to start the search then "one" to locate it ...
  (reverse-i-search)`one': echo one
  ... type in control-o to operate on it and get the next line ...
  $ echo two
  ... type in control-o to operate on it and get the next line ...
  $ echo three

The bash documentation for the says:

       operate-and-get-next (C-o)
              Accept the current line for execution and fetch the next
              line relative to the current line from the history for
              editing.

Bob
