linux as5下用./test.sh执行SH时报错，syntax error near unexpected token '('
test.sh中的内容为：
#!/bin/sh
cd /opt/oracle/dbbak
rm -rf /opt/oracle/dbbak/dbbak.dmp
exp test/test tables=(t_test) file=/opt/oracle/dbbak/dbbak.dmp log=/opt/oracle/dbbak/dbexp.log


------解决方法--------------------------------------------------------
每一步分开执行了吗？每行命令后面加下“;”
------解决方法--------------------------------------------------------
把() 给去了，

exp test/test tables=t_test file=/opt/oracle/dbbak/dbbak.dmp log=/opt/oracle/dbbak/dbexp.log
------解决方法--------------------------------------------------------
exp test/test tables=＼(t_test＼) file=/opt/oracle/dbbak/dbbak.dmp log=/opt/oracle/dbbak/dbexp.log
