Running stored procedure from unix shell

Question

Hi
I have a stored procedure proc1 stored in a file, code1.txt in my home directory /home/user. How do i execute this file which contains the stored procedure from unix shell? I would really appreciate it if somebody gives me the complete shell script to accomplish the above task.
Thanks.

To put everything together into a single posting:
The EXEC command is a SQL*Plus macro command. It is not a SQL or PL/SQL command.
The only way to execute a stored proc from a client, is to wrap the call in an anonymous PL/SQL block. I.e you need a BEGIN and END PL/SQL wrapper around the call.
E.g.BEGIN
  -- calling a stored proc to start leave processing
  scott.StartLeaveProcessing;
END;The EXEC macro in SQL*Plus does this automatically for you. Thus less typing. But do not confuse this command with the PL/SQL language.
Second issue. Use bind variables when making calls from clients. And not just for SQL statements, but also for PL/SQL. Unfortuantely this tends to be a hack in SQL*Plus due to the way SQL*Plus itself treats its bind variable assignments. But in principle, this is what you should do when calling an Oracle stored proc from a client:
SQL> -- define a host variable
SQL> var EMPID varchar2(100)
SQL> var FROM_DEPT number
SQL> var TO_DEDPT number;
SQL>
SQL> -- assign values to these (this is where SQL*Plus hacks it)
SQL> exec :EMPID := 100;
SQL> exec :FROM_DEPT := 1;
SQL> exec :TO_DEPT := 2;
SQL>
SQL> -- now make the stored proc call for moving employee 100 from
SQL> -- department 1 to department 2
SQL> EXEC scott.EmployeeTransfer( :EMPID, :FROM_DEPT, :TO_DEPT );
SQL>To do this from a Unix shell script:
#!/bin/bash
# environment variables
# --> put environment such as ORACLE_HOME, ORACLE_SID, TWO_TASK
# etc. here <--
# redirect STDIN from TTY (keyboard typewriter device) to the input from
# this file - which means SQL*Plus will not read from the keyboard but read
# from this file its input until the EOF marker/text is encountered
sqlplus -s /nolog << EOF
connect scott/tiger
var EMPID varchar2(100)
var FROM_DEPT number
var TO_DEDPT number;
exec :EMPID := 100;
exec :FROM_DEPT := 1;
exec :TO_DEPT := 2;
exec scott.EmployeeTransfer( :EMPID, :FROM_DEPT, :TO_DEPT );
exit;
EOF
#eof
