Set alias with quotes and double quotes in command
提问by voy
I want to set an alias for the command:
我想为命令设置别名：
expect -c 'spawn ssh usr@ip -p 57022 ; expect password ; send "pass\n" ; interact'
but quotes from alias alias_name=""and from command doesn't like each other.
但引号 fromalias alias_name=""和 from command 不喜欢对方。
I tried combinations with ', "and `, but all of these failed.
How can I do that?
我尝试了与',"和 ` 的组合，但所有这些都失败了。我怎样才能做到这一点？

A simple solution is to create a function, instead of an alias:
一个简单的解决方案是创建一个函数，而不是一个别名：
function function_name() {
expect -c 'spawn ssh usr@ip -p 57022 ; \
expect password ; send "pass\n" ; interact'
}
So you can call function_name, and it will work just as fine as with an alias.
所以你可以调用function_name，它会像使用别名一样工作。
If you still want to use an alias, just escape the inner "'s:
如果您仍然想使用别名，只需转义内部"的：
alias alias_name="expect -c 'spawn ssh usr@ip -p 57022 ; expect password ; send \"pass\n\" ; interact'"
and it should work.
它应该工作。
