When downloading in a detached screen session the --quiet option must be used.

[GoogleCodeExporter]

Hi,

Thanks for the helpful utility! This isn't really a bug, but I can't edit the 
wiki so I thought I'd mention it here.

What steps will reproduce the problem?
1. Start a new screen session:
  screen
2. Start downloading from Gauge Connection with qcdutils:
  ./qcdutils.py download_link
3. Detach the screen session:
  [Ctrl]+a d
4. Re-attach to the screen session:
  screen -R

What is the expected output? What do you see instead?
I expected the download to continue. Instead, qcdutils crashes with the 
following output:

Thanks for the helpful utility! But there is something I don't know how to deal 
with.  When I download some files: for example, the MILC configuration  
from u_MILC_2064f21b679m020m050.1002 to u_MILC_2064f21b679m020m050.1032.
I shut down my computer, next day, when I resume the download process, 
it still continue from  u_MILC_2064f21b679m020m050.1002, 
can you tell me how to resume from u_MILC_2064f21b679m020m050.1038 
instead from  u_MILC_2064f21b679m020m050.1002.

Thanks

Hi,

I didn't write the utility, I'm just another grateful user. I'm also unsure 
about what is causing your problem. 

When I run the utility multiple times in the same directory it checks which 
files have already been downloaded and doesn't download them again.

Can you tell me exactly what commands you are running?

Andy

I find this problem, because I delete the qcdutils.catalog.

Thanks,
