Using a shell script, can I watch a folder and block program execution until a file in a certain folder changes?

    inotifywait /path/to/file

    Example:

    inotifywait test.file; echo "test.file just changed"

    Then in another terminal do something like touch test.file

      Thanks for your hint! After some experimentation and man page reading, this was what I was interested in:

      inotifywait --event modify,create ./targetfolder/; echo "new change, that I am interested in, occurred in targetfolder";

      I was interested in both file modification and file creation events.
