How to launch a shell script with an emacs keybinding, passing the word under the cursor as a variable - linux

Question

Executing the script below on osx via emacs, didn't work, I got a permission denied message, the answer to this question solved that problem: https://stackoverflow.com/a/12276562/912475
Tldr: How can I set up a system to automatically pass the word under the cursor in emacs directly to my shell script as a variable and then run that script?
I've created a somewhat rudimentary system for "linking" to folders from plain text files in a robust way. It uses a timestamp that's generated by a script and then set as the "value" of the clipboard. From the clipboard, the timestamp is then pasted into a txt with related notes and into the name field of a folder.
To find the folders when reading the txt I use an emacs function with a keybinding that makes it possible to copy the timestamp (as a word, it's all numbers) to the clipboard and search for it in spotlight (on osx). What I'd like to do instead is to automatically launch a shell script that searches for a directory whose name ends with that string and then opens it. I already have a script that does something like that, but I don't really know how to tie the elisp function and shell script together. I'd greatly appreciate a solution that works on either osx and linux (I use both). It will probably be easy to "port" a solution that works on either one for use with the other.
This is the emacs function for copying a word under the cursor:
;;; function for copying a word under the cursor http://www.emacswiki.org/emacs/CopyWithoutSelection
(global-set-key (kbd "C-c o") (quote copy-word))
(defun copy-word (&optional arg)
"Copy words at point into kill-ring"
(interactive "P")
(copy-thing 'backward-word 'forward-word arg)
;;(paste-to-mark arg)
)
This is the script to find and open the directory whose name ends with the timestamp:
#!/bin/bash
PATH=/opt/local/bin:/opt/local/sbin:$PATH #need this to make the gnu coreutils work on osx
file_number="20130812193913"
path_to_open=$(gfind ~/x/ | grep -e $file_number$) # $ means the end of the line, makes it possible to search for directories without finding their content
open "${path_to_open}"
An edited version of the script that accepts arguments from the commandline like this:
me$ sh script_path.sh 20130812193913
The script:
#!/bin/bash
PATH=/opt/local/bin:/opt/local/sbin:$PATH #need this to make the gnu coreutils work on osx
file_number=$1
echo $file_number
path_to_open=$(gfind ~/x/ | grep -e $file_number$) # $ means the end of the line, makes it possible to search for directories without finding their content
open "${path_to_open}"

You could try something like this:
(defvar script-name "/foo/bar/my-script")
(defun call-my-script-with-word ()
(interactive)
(shell-command
(concat script-name
" "
(thing-at-point 'word))))
(global-set-key (kbd "C-c o") 'call-my-script-with-word)
