在linux执行exp命令报错，如下：
[oracle
]$ exp system/****@orasid file
=/home/oracle/dump/exp.dmp owner
=(a,b,c,d
) log
=/home/oracle/dump/exp_a_b_c_d.log buffer
=102400000
-bash: syntax error near unexpected token `
('
经查是linux系统执行命令的小括号需要转义，改成如下命令，正常执行
[oracle
]$ exp system/****@orasid file
=/home/oracle/dump/exp.dmp owner
="(a,b,c,d)" log
=/home/oracle/dump/exp_a_b_c_d.log buffer
=102400000
也可以在小括号前加 \ 转义:
[oracle
]$ exp system/****@orasid file
=/home/oracle/dump/exp.dmp owner
=\
(a,b,c,d\
) log
=/home/oracle/dump/exp_a_b_c_d.log buffer
=102400000
