-bash: syntax error near unexpected token `('
提问by Adam_G
I'm trying to run the query below in Terminal on OSX. It keeps returning:
我正在尝试在 OSX 上的终端中运行以下查询。它不断返回：
-bash: syntax error near unexpected token `('
I'm sure I'm overlooking something very dumb. If someone could point me in the right direction, I'd appreciate it. The command includes the SQL query for the program to execute:
我确定我忽略了一些非常愚蠢的东西。如果有人能指出我正确的方向，我将不胜感激。该命令包括要执行的程序的 SQL 查询：
java -Xmx16g -cp .:lib/* edu.cuny.util.VectorToInstancesConverter train HandednessJ48 “SELECT * FROM collection1.Session1 WHERE Subj_Id!=402 and Subj_Id not in ( select Subj_id from collection1.Session2) AND Subj_Id IN ( SELECT Subj_Id FROM collection1.userdata WHERE 'DominantHand' = 'l' OR 'DominantHand' = 'r')” 12 J48

The problem is when you use "bash tries to evaluate anything within it instead you should use ', try this:
问题是当您使用"bash 尝试评估其中的任何内容时，您应该使用'，试试这个：
java -Xmx16g -cp .:lib/* edu.cuny.util.VectorToInstancesConverter train
HandednessJ48 'SELECT * FROM collection1.Session1 WHERE Subj_Id!=402
and Subj_Id not in ( select Subj_id from collection1.Session2) AND
Subj_Id IN ( SELECT Subj_Id FROM collection1.userdata WHERE
'DominantHand' = 'l' OR 'DominantHand' = 'r')' 12 J48
or as @bhesh has specified you can delimit the characters which bash will try to evaluate :
或者正如@bhesh 指定的那样，您可以分隔 bash 将尝试评估的字符：
java -Xmx16g -cp .:lib/* edu.cuny.util.VectorToInstancesConverter train
HandednessJ48 "SELECT * FROM collection1.Session1 WHERE Subj_Id!=402
and Subj_Id not in \( select Subj_id from collection1.Session2\) AND
Subj_Id IN \( SELECT Subj_Id FROM collection1.userdata WHERE
'DominantHand' = 'l' OR 'DominantHand' = 'r'\)" 12 J48
