It might take a while before anything gets outputted. I think it might also be good if you try the –dry-run option first just so that you’d know what to expect.
Here’s a sample output from one of my runs. It’s already been scoured clean, so there’s nothing to do.
Where ${uname} and ${pword} are my username and password respectively, and $dryrun is either –dryrun or the empty string.
The output is then saved to a log file with the name pattern username_timestamp.
Also, I noticed that you’re using the gpdr-export option. I think there’s some wonkiness regarding that? I am not sure though. I still recommend using the –dryrun option first just to see what’s up (without actually doing any changes to your account.
EDIT:
I forgot to clarify, shreddit-linux is what I named the executable file I got from the repository.
I tried the dry run but didn't get anything back after running command. I must just have to go the tedious route of deleting comments manually over the year from time to time.
Before you give up on it, you might want to check on your shreddit.env file. The command line parameters override the stuff in there, but it might be a good idea to check anyways.
