Applescript在执行shell脚本时返回“非零状态下退出的命令”

我正在处理一个Applescript，当它执行命令检查命令的结果后，我执行它，它会提示一条消息（在AppleScript编辑器中）; Expected expression but found “error”.。Applescript在执行shell脚本时返回“非零状态下退出的命令”

我该如何备份并检查命令是否与The command exited with a non-zero status.相同，以便我可以做其他事情，如果它与错误消息相同？

do shell script "echo \"stats\" | nc localhost 11211" password "~password~" with administrator privileges 

if error = "The command exited with a non-zero status." then 
    display dialog "Returned zero" 
else if result = "The command exited with a non-zero status." then 
    display dialog "Returned zero" 
else if result = "" then 
    do shell script "memcached -d -l 127.0.0.1 -p 11211 -m 64" 
    display dialog "Memcached Started" 
else 
    do shell script "killall memcached" with administrator privileges 
    display dialog "Memcached Stopped" 
end if

编辑：更新版本

set error to do shell script "echo \"stats\" | nc localhost 11211" password "~password~" with administrator privileges 

if error = "The command exited with a non-zero status." then 
    do shell script "memcached -d -l 127.0.0.1 -p 11211 -m 64" 
    display dialog "Memcached Started" 
else 
    do shell script "killall memcached" with administrator privileges 
    display dialog "Memcached Stopped" 
end if

你的具体问题是在使用单词 “错误” 作为一个变量。错误是applescript的一个特殊词，因此它不能用作变量。

但是，即使您解决了这个问题，您的代码仍然无法正常工作。您用try块捕获错误消息。请注意，“theError”包含错误消息...

try 
    do shell script "echo \"stats\" | nc localhost 11211" password "~password~" with administrator privileges 
on error theError 
    if theError is "The command exited with a non-zero status." then 
     do shell script "memcached -d -l 127.0.0.1 -p 11211 -m 64" 
     display dialog "Memcached Started" 
    else 
     do shell script "killall memcached" with administrator privileges 
     display dialog "Memcached Stopped" 
    end if 
end try
