Code:
$ sqlplus -S <<! | while read; do printf 'line: %s\n' "$REPLY"; done
> / as sysdba
> select sysdate from dual;
> !
line:
line: SYSDATE
line: ---------
line: 08-JAN-13
line:

Or:
Code:
$ sqlplus -S <<! |
> / as sysdba
> select sysdate from dual;
> !
> while read; do
>   printf 'line: %s\n' "$REPLY"
> done
line:
line: SYSDATE
line: ---------
line: 08-JAN-13
line:

In your case it would be something like this:
Code:
"$HOME"/sqlplus << EOF | 
command
select * from xyz;
exit
EOF 
while IFS= read -r; do
  printf '%s\n' "$REPLY" | grep whatever
done

P.S. Drop the -r option of read if your shell doesn't support it.

NAME
asa -- interpret carriage-control characters. SYNOPSIS
asa [file ...] DESCRIPTION
The asa utility reads files sequentially, mapping FORTRAN carriage-control characters to line-printer control sequences, and writes them to the standard output. The first character of each line is interpreted as a carriage-control character. The following characters are interpreted as follows: <space> Output the rest of the line without change. 0 Output a <newline> character before printing the rest of the line. 1 Output a <formfeed> character before printing the rest of the line. + The trailing <newline> of the previous line is replaced by a <carriage-return> before printing the rest of the line. Lines beginning with characters other than the above are treated as if they begin with <space>. EXAMPLES
To view a file containing the output of a FORTRAN program: asa file To format the output of a FORTRAN program and redirect it to a line-printer. a.out | asa | lpr DIAGNOSTICS
The asa utility exit 0 on success, and >0 if an error occurs. SEE ALSO
f77(1) STANDARDS
The asa utility conforms to IEEE Std 1003.2-1992 (``POSIX.2''). AUTHORS
