避免 ‘sudo echo xxxx >’ 时候 出现 “permission denied”

➜  ~ echo "/opt/nfs 10.10.10.*(rw,all_squash,sync)">>/etc/exports

zsh: permission denied: /etc/exports

 

 

解决办法：

1）sudo sh -c ' echo "/opt/nfs 10.10.10.*(rw,all_squash,sync)" >> /etc/exports’

 

2）echo "/opt/nfs 10.10.10.*(rw,all_squash,sync)" |sudo tee /etc/exports

     echo "/opt/nfs 10.10.10.*(rw,all_squash,sync)" |sudo tee -a /etc/exports    -a：append 追加

 

3）提升权限
