Calling sqlplus from unix script

Question

hello,
I am trying to connect to sqlplus from shell:
#!/bin/bash
SERVER_NAME=ORA1
sqlplus -s SYS/PASSWD@$SERVER_NAME AS SYSDBA <<EOF
select * from v\$version
EOF
However, the output is:
Usage: SQLPLUS [ [<option>] [<logon>] [<start>] ]
where <option> ::= -H | -V | [ [-L] [-M <o>] [-R <n>] [-S] ]
<logon> ::= <username>[<password>][@<connect_string>] | / | /NOLOG
<start> ::= @<URI>|<filename>[.<ext>] [<parameter> ...]
"-H" displays the SQL*Plus version banner and usage syntax
"-V" displays the SQL*Plus version banner
"-L" attempts log on just once
"-M <o>" uses HTML markup options <o>
"-R <n>" uses restricted mode <n>
"-S" uses silent mode
Do you have any idea about that?
Thanks.

Answer 1

the connection was establised. thanks.
any idea why I am getting the same output twice for the following statement?
#!/bin/bash
ORACLE_SID=ORA1
export ORACLE_SID
sqlplus -s SYS/PASSWD@$ORACLE_SID AS SYSDBA <<EOF
select SUM(bytes) from dba_data_files where tablespace_name = 'tts1';
EOF
the output is
SUM(BYTES)
3.4773E+10
SUM(BYTES)
3.4773E+10
