By default import will only try to append the data.
If the table already exists it will error out (using ignore=y will suppress only the error being displayed due to existence of table).
If the table is constrained (PK for example) and if the condition is not met, the row will not be appended.

You can let Import prompt you for parameters by entering the IMP
command followed by your username/password:

     Example: IMP SCOTT/TIGER

Or, you can control how Import runs by entering the IMP command followed
by various arguments. To specify parameters, you use keywords:

     Format:  IMP KEYWORD=value or KEYWORD=(value1,value2,...,valueN)
     Example: IMP SCOTT/TIGER IGNORE=Y TABLES=(EMP,DEPT) FULL=N
               or TABLES=(T1:P1,T1:P2), if T1 is partitioned table

USERID must be the first parameter on the command line.
