------解决方案--------------------
建立一个参数文件mypar.par

directory=mydir
dumpfile=myfile.dmp
logfile=myfile.log
exclude=TABLE:"IN('TABLE1'，'TABLE2')"

然后导出
expdp user/passwd parfile=mypar.par

引用楼主 ddbaby 的帖子:

高分求unix下expdp导出exclude的正确语法！！！ 
oracle文档上公布的：EXCLUDE=OBJECT_TYPE[:NAME_CLAUSE][,....] 
但实际操作中直接套用exclude=TABLE:(table1,table2)不行 
exclude=TABLE:"in('table1'，'table2')" 也行不通 
加入各种/转义字符也不行，求正确语法！
