完美解决 bash: /dev/fd/63: No such file or directory

bash: /dev/fd/63: No such file or directory root

安装64为的ubuntu,在使用root权限调用bash出现错误

root@hostname:~ sudo bash <(wget -q0 https://raw.githubusercontent.com/ubports/unity8-desktop-install-tools/master/install.sh) 
bash: /dev/fd/63: No such file or directory root

解决方案：

sudo bash < <(wget -q0 https://raw.githubusercontent.com/ubports/unity8-desktop-install-tools/master/install.sh)

需要注意bash中<<，<<<和< <之间有什么区别点击查看
