help me!!

Hello,

My name is rong xie. I am a Student at TU-Munich.
I have a question to Postgresql an Linux.
e.g:
for IBM DB2: I can write a test.sql file.

--test.sql
connect to database1;
set schema xie;
select * from table1;
insert table1 value('rong','xie',22);
select * from table1;
terminate;

Then I can execute the file "test.sql" in terminal.
db2 -tvf test.sql

In mysql: I can execute it so.
mysql > test.sql

How can I execute it in Postgresql?
is there similar command in linux for Postgresql?

Thank you very mach!

Best wish!

rong xie
