UNIX for Dummies Questions & Answers

Hey Guys


from the below script what I understood is we are sending the the first parameter as input to the main (){} file
main > $LOGFILE 2>&1
but can we send two or three parameter as input to this main file as
main > $LOGFILE 2>&1 2>&2 like this

Can any one plz help I need to writ a script which takes three parameters

#!/usr/bin/ksh
DIRNAME=/web/local/orderlink/linkload/script
LOGDIR=/web/local/orderlink/linkload/logs
LOGFILE=$LOGDIR/process_stuck_csos.log
NUMARGS=$#
ARGI=$1

main()
{
DATESTAMP=`date +%Y%m%d%H%M%S`
SQL_TEMP_FILE=$DIRNAME/tmpcsosclean.sql
SQL_A="SET SERVEROUTPUT ON;\n
DECLARE\n
TYPE OrderList IS TABLE OF S_ORDR.ORDR_ID%TYPE INDEX BY BINARY_INTEGER;\n
listOrders OrderList;\n
\n
BEGIN\n
"

SQL_B="\nFORALL i IN listOrders.FIRST..listOrders.LAST\n
UPDATE s_ordr set ORDR_STAT_TXT = 'CSOS REJECTED'\n
where ordr_id = listOrders(i)\n
and ORDR_STAT_TXT = 'CSOS SIGNED/IN-PROG';\n
DBMS_OUTPUT.PUT_LINE(SQL%ROWCOUNT || ' row(s) actually updated.' );
COMMIT;
\n
END;
\n/
\nEXIT
"

. $DIRNAME/set_env.ksh

echo "----------------------------------------------------------------------"
echo $DIRNAME"/"$0
echo $DATESTAMP
echo "Using:"$ORACLE_SID

n=`grep -c '^[0-9]\{1,10\}$' $infile`
echo $n "order id(s) found to process in" $infile

if [ $n -lt 1 ]; then
echo "Nothing to do..."
exit 0;
fi

echo "Generating SQL";


echo $SQL_A > $SQL_TEMP_FILE
grep '^[0-9]\{1,10\}$' $infile | awk '{print "listOrders("NR") := "$1";"}' >> $SQL_TEMP_FILE
echo $SQL_B >> $SQL_TEMP_FILE

echo "Running SQL_PLUS"

sqlplus -s / @$SQL_TEMP_FILE

mv $SQL_TEMP_FILE $LOGDIR/proc_stuck_csos.sql.log
}

if [ $# != 1 ]; then
echo "Usage: $0 input-file"
exit 1
else
if [ ! -r $ARGI ]; then
echo "Error: File not found, or file unreadable!"
exit 1
else
infile=$ARGI
fi
fi

main > $LOGFILE 2>&1



Thanks in advance
I am desperate needed to code as quickly as possible
