你的问题:你的整个命令都放在单引号中——显然是为了 bash 表达式在服务器上而不是在本地展开.

Your problem: Your entire command is put into single quotes – obviously so that bash expressions are expanded on the server and not locally.

但这也适用于您的 $1.

简单的解决方案:通过将本地变量包装到单引号中来中断"引用.

Simple solution: "Interupt" the quotation by wrapping your local variable into single quotes.

ssh root@192.168.0.1 'echo "#date added $(date +%m/%d/%Y)" >> /var/named/chroot/etc/named.conf; echo "zone "'$1'" { type master; file "/etc/zone/dummy-block"; };" >> /var/named/chroot/etc/named.conf'

注意:"$1" → "'$1'".
