"Recent Items" stack in Dock

Question

I typed the required commands into Terminal to create a Recent Items stack in the Dock, which I then limited to recent documents.
One morning when I booted, the Recent Documents stack was missing. I dragged the "empty space" where it had been out of the Dock and tried retyped the Terminal commands to regain the recent items stack:
first, <defaults write com.apple.dock persistent-others -array-add '{ "tile-data" = { "list-type" = 1; }; "tile-type" = "recents-tile"; }’>
and then, when that was not successful, <defaults write com.apple.dock persistent-others -array-ad>.
I followed each one with "killall Dock".
All that happened, both times, was the disappearance of ALL my stacks from the Dock.
Am I typing these commands wrong, or what? I also notice that sometimes after typing one into Terminal, my original prompt doesn't reappear but only a < sign.
What should I do to get my recent items stack back?

Hi,
1) go to terminal
2) type in pico
3) type in the following script (or copy it!)
!#/bin/bash
*defaults write com.apple.dock persistent-others -array-add '{ "tile-data" = { "list-type" = 1; }; "tile-type" = "recents-tile"; }'*
*killAll Dock*
4) save file as recents.sh
5) give it executable rights *chmod u+x recents.sh*
6) execute it ./recents.sh
7) keep the file for later use (if you want)
