Describe the bug

these commands

/home/user/.local/bin/archivebox list --html > /home/user/archivebox/index.html
/home/user/.local/bin/archivebox list --html

throw an error

print(output)
OSError: [Errno 9] Bad file descriptor

github.com/ArchiveBox/ArchiveBox@f5739506f6/archivebox/main.py (L883C4-L883C4)

I changed print(output) to

        with open('/home/user/archivebox/index.html','w') as file:
            file.write(output)

and the problem was resolved. i guess import sys; sys.stdout = open('stdout.txt', 'w') would also work.

i suspected that the stdout pipe got filled up causing the error and i can not reliably reproduce this error

std flush before print also seems to mitigate this problem

Env:
my archivebox is on a low budget vps, and the archive folder is actually remote mounted google drive folder.

Steps to reproduce

Screenshots or log output

ArchiveBox version

replace this line with the *full*, unshortened output of running `archivebox version`

btw how to specify the latest snapshot first in --sort when outputing static html? --sort=timestamp does the opposite

I need the output of archivebox version to help, please edit your post and add it.

use --sort=-timestamp
