我在 docker exec -it owncloud bash 下跑 echo -e "\n<Directory \"/var/www\">\nAllowOverride All\n</Directory>" >> /etc/apache2/conf-available/docker-php.conf;
內容會多出 \n<Directory \"/var/www\">\nAllowOverride All\n</Directory>

我直接跑 docker exec -it owncloud /bin/sh -c 'echo -e "\n<Directory \"/var/www\">\nAllowOverride All\n</Directory>" >> /etc/apache2/conf-available/docker-php.conf'
內容會多出 -e \n<Directory \"/var/www\">\nAllowOverride All\n</Directory>
