So not quite.
has something to do with 1476 being modded down by 256 (or something - i'll let somebody more knowledgeable comment on that)
My reply was geared towards providing the OP with an exit code other than zero from sqlplus in case of failure...because the default behavior of sqlplus is to return zero to its environment irrespective of what goes on inside of it. Also the sqlcode returned to the shell will always be truncated to stay within the shell limits <0-255>. In the example you provided the sqlcode for the ORA error is 1476 which is not mod'd down...but is truncated bitwise leaving only the 8 least significant bits. As 1476 is 0x000005C4 and its 8 LS bits are 0xC4 giving a decimal value of 196. However the exact sqlcode will still be be dumped to the logfile and can be extracted from there...

Code:
# error codes to look for (add/remove what you want to look for)
ERRCODES="(ORA-|EXP-|IMP-|KUP-|MOD-|PLS-|SP2-|SQL-|TNS-)"

sqlplus -s myid@mydb @gg.sql   2>&1 >> ${LOGFILE}
ERR=$?

ERRC=`egrep "${ERRCODES}" ${LOGFILE} | wc -l`

and then you have an error if either:
[ $ERR -ne 0 ] || [ $ERRC -ne 0 ]
Yes it can be re-directed to the logfile and viewed in there...

Your password will be visible to anyone on the same server, via "ps -ef" command.

If you're using an automated script, you really should consider externally defined ids, and then just use:

Code:
sqlplus -s  / @${DIR}/query.sql > outputfile

I too agree with the above comments...
