【问题描述】：
遇到的问题：
命令* * * * * $(command -v docker) docker run --rm -it --env-file=/home/ubuntu/.env ghcr.io/sebastix/crypto-dca:latest buy 10 ADA 不会启动。这是在文件中测试的
- crontab -e
- sudo crontab -e
- sudo nano /etc/crontab
日志电子邮件始终打印：
unknown flag: --rm
See 'docker --help'.
Usage: docker [OPTIONS] COMMAND
A self-sufficient runtime for containers
Options:
--config string Location of client config files (default "/root/.docker")
...
如果我手动运行命令（没有 cron），它就像一个魅力 (docker run --rm -it --env-file=/home/ubuntu/.env ghcr.io/sebastix/crypto-dca:latest buy 10 ADA)。同样适用于docker run --rm -it --env-file=/home/ubuntu/.env ghcr.io/sebastix/crypto-dca:latest balance????
我的系统：
我在 Raspberry Pi 4 上运行 ubuntu OS 20.04.3 LTS 64bit。
Docker 本身是本地安装的 (sudo apt install docker.io)
Docker compose 是使用 Python3-pip 设置的（你知道，docker 的 aarch64 架构问题......）

sudo crontab -e的输出：
# Edit this file to introduce tasks to be run by cron.
#
# Each task to run has to be defined through a single line
# indicating with different fields when the task will be run
# and what command to run for the task
#
# To define the time you can provide concrete values for
# minute (m), hour (h), day of month (dom), month (mon),
# and day of week (dow) or use '*' in these fields (for 'any').
#
# Notice that tasks will be started based on the cron's system
# daemon's notion of time and timezones.
#
# Output of the crontab jobs (including errors) is sent through
# email to the user the crontab file belongs to (unless redirected).
#
# For example, you can run a backup of all your user accounts
# at 5 a.m every week with:
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/

【问题讨论】：
-
如果您删除第二个
docker出现，那么它会起作用吗？$(command -v docker)的输出已经是 Docker 二进制文件的路径。所以试试：$(command -v docker) run --rm -it --env-file=/home/ubuntu/.env ghcr.io/sebastix/crypto-dca:latest buy 10 ADA -
@MarkoE：这也行不通。错误：“输入设备不是 TTY”。我假设，
docker命令是强制性的，无论路径中是否出现相同的情况（在我的情况下：command -v docker打印/usr/bin/docker）。 -
您需要删除
-it部分，因为您将其作为 cron 脚本运行。 -
@MarkoE 在没有
-it的情况下运行仍然无法工作。错误：unknown flag: --rm命令：* * * * * $(command -v docker) docker run --rm --env-file=/home/ubuntu/.env ghcr.io/sebastix/crypto-dca:latest buy 10 ADA -
@MarkoE：非常感谢您的耐心等待！这样就解决了问题。工作命令：
* * * * * $(command -v docker) run --rm --env-file=/home/ubuntu/.env ghcr.io/sebastix/crypto-dca:latest buy 10 ADA --yes（我已经附加了--yes，所以它会自动执行购买而不要求确认。
