crontab can't run qbt, why?

[PHCSJC]

this is success in shell, I have config user password url by "qbt settings set": qbt torrent list

this is also success in crontab: 03 13 * * * qbt torrent --help >>/tmp/ccc 2>>/tmp/ccc

but, this is failed in crontab, never running, /tmp/ccc is empty 03 13 * * * qbt torrent list >>/tmp/ccc 2>>/tmp/ccc

thanks!

my system is debian 10 x64. qbt --help 1.5.19350.1

I need to investigate why it outputs nothing.

Are you running qbittorent and qbt on the same machine and on the default port? If not, you may need to explicitly specify --url parameter in the command if running from crontab.

As there is no screen available when the command is run by cron, it will fail with the default output format as it tries to get the screen witdh. JSON or CSV output format must be used for non-interactive scenarios, e.g.

qbt torrent list -F json
