ssh远程执行awk时的匹配问题

registcn

1) echo $(ssh testhost "echo haha lala |awk '\$2~/lala/{print \$2}'&& echo ok")
lala ok
2) echo $(ssh testhost "echo haha baba |awk '\$2 !~/lala/{print \$2}'&& echo ok")            
-bash: !~/lala/{print: event not found
3) echo `ssh testhost "echo haha lala |awk '\$2 ~/lala/{print \$0}'&& echo ok"`   
awk: cmd. line:1:  ~/lala/{print -bash}
awk: cmd. line:1:  ^ syntax error

见上述现象描述，测试发现，$()中ssh远程时用awk的~可以，!~不可以，而若用反引号``,则连~都不可以了。
求两个说法：
2）中怎么摘$()中用!~
3)  中怎么用~

$ echo $(ssh localhost "echo haha lala | awk '\$2!~/lala/{print}' && echo ok ")
bash: !~/lala/{print}': event not found

$ echo $(ssh localhost 'echo haha lala | awk "!\$2~/lala/{print}" && echo ok ')
.... password:
ok

楼主不想看到这种变通的方法，其实之前那个帖子就是这么解决的。还是想看下，如果就按双引号ssh，应该怎么写

$ echo $(ssh localhost "echo haha lala | awk '$2!~/lala/{print}' && echo ok ")
bash: !~/lala/{print}': event not found
$ echo $(ssh localhost "echo haha lala | awk 'match(\$2,/lala/)==1{print}' && echo ok ")
haha lala ok

$ echo $(ssh localhost "echo haha lala | awk 'match(\$2,/lala/)<1{print}' && echo ok ")
ok
