bash wait for open app to complete before continuing

I have a problem with timing in a BASH script.

#!/usr/local/bash
open /apps/my.app #this generates a text file; may take a few seconds. Then the app closes.
sed 's/....' new_text_file.txt; #this modifies the text file

How best do I wait for the app to finish properly before the sed takes place? Currently the open command sets up a background task like a NOHUP, and the script proceeds immediately to the sed. If it helps, the app is an OSX Automator workflow converted to an app.

Use the -W flag of open to wait for the app to quit:

#!/usr/local/bash
open -W /apps/my.app #this generates a text file; may take a few seconds. Then the app closes.
sed 's/....' new_text_file.txt; #this modifies the text file
