linux常用命令(2)

sed 在匹配hub.xxx.io的行首添加#:

sed -i '/hub.xxx.io/s/^/#&/' /etc/hosts

sed去掉匹配hub.xxx.io行首的#:

sed -i '/hub.easystack.io/s/^#//' /etc/hosts

sed刪除匹配行:

sed -i "/hub.xxx.io/d"

遠程執行多行命令:

    sshpass -p xxx ssh -o StrictHostKeyChecking=no root@xxx << remotessh
sed -i '/hub.xxx.io/s/^/#&/' /etc/hosts
echo "172.0.0.1 hub.xxx.io" >> /etc/hosts
docker pull hub.xxx.io/arm64/nginx-ingress-controller:0.9.0-beta.15
docker pull hub.xxx.io/arm64/nginx-ingress-controller:0.24.1
sed -i "/172.0.0.1 hub.xxx.io/d"
sed -i '/hub.xxx.io/s/^#//' /etc/hosts
remotessh
