Docker exec pipe没有这样的文件或目录

Question

出于某种原因，>找不到文件test.txt，但是ls却找到了。

$ docker exec mycont ls /headless/Desktop
test.txt
$ docker exec mycont ls /headless/Desktop > /headless/Desktop/test.txt
-bash: /headless/Desktop/test.txt: No such file or directory

Answer 1

docker exec mycont bash -c "ls /headless/Desktop > /headless/Desktop/test.txt"

您希望docker在容器中而不是在主机上查找文件
