Getting number of records from a table

I am doing a loading process. I am loading data from a Oracle source to Oracle target.

For example there is an SQL statement:

Insert into emp_1
Select * from emp_2 where deptno=20;

In this case my source is emp_2 and loading into my target table emp_1. This process is automated. Now I want a unix script which should generate a file after loading into the target is completed.

The file will have:

Number of records in emp_1 = <<>>
Number of records in emp_2 = <<>>

i.e. I want a script that would generate a file with the number of records in source and target table.

Thanks in advance.

if you have the file, the you can use wc or grep or awk command to count the no. of lines.

wc -l filename
grep -c . filename
awk 'END{print NR}' filename

Thanks for the reply.

I want the count from Oracle table to a Unix file, not the count in a file.

For example a table has 300 records...I want script which counts the number of records from the table.
