I didn't even notice the higher level methods. I changed the
retrieval line to:
ftp.nlst("testfile*.txt")
This works great. The result is even captured in an array. I really
have no idea what the difference between a LIST and NLST is within
FTP. Never delved that deep into it. I did notice that an NLST will
return a specific FTP code if a file doesn't exist, whereas a LIST
doesn't. So, I ended up using NLST as that'll generate an
ftplib.error_perm exception. Based on if the job cares if a file is
not available or not (some do, some don't), I'll either exit, or
continue on with the file loop.
Anyway, thanks again, works perfectly, next time I'll try to scroll
down and read a bit more prior to posting!
