Downloading only specific files with command script
First time poster here. I am new to scripts so bear with me. I am trying to edit a script that someone else wrote who used to work here. The problem I am having is that one of the ftp sites has changed and I need to set it up to download file from the new site. In this new site the folder my files are in has a sub folder with archives of past files (its a weekly radio show with audio files) What I need is for only the current week's files to be downloaded and NOT the sub folder.
Here is the command I have currently have.
cd "/home/nrtsyndication/nrtsyndication.com/syndication/Christian_Music_Rewind/"
This command successfully downloads all the files within that subfolder. However there is another folder within the "Christian_Music_Rewind" folder that has large archive files. How can I change this command so it only downloads the audio files within the this specific sub folder and not the other folder another step down?
