shell腳本執(zhí)行出錯(cuò)

dqjhl

我有一個(gè)腳本，執(zhí)行時(shí)提示：backup.sh: syntax error at line 12: `(\' unexpected 。腳本如下：
ORACLE_BASE=/export/home/oracle
ORACLE_HOME=/export/home/oracle/OraHome1
ORACLE_OWNER=oracle
ORACLE_SID=A2DBCENTER
export ORACLE_BASE
DBA=$ORACLE_BASE/admin
export ORACLE_HOME
PATH=$PATH:$ORACLE_HOME/bin:/usr/local/bin
ORACLE_OWNER=oracle
export ORACLE_SID
ORACLE_OWNER=oracle
export ORACLE_SID
export PATH
declare t=$(\"date\"|nawk \'{print $1}\')
case \"$t\" in
\"Sun\")

        $ORACLE_HOME/bin/rman target / nocatalog << EOF
        run {
        backup incremental level 0 database format \'/data3/orabak/L0_%d_0_%s.bak\' plus archivelog format=\'/data3/orabak/L0_%d_arc_%s
.bak\' ;
        backup tag \'L0_spfile_bak\' format \'/data3/orabak/L0_%d_SPFILE_s.%s.bak\' spfile;
        backup tag \'L0_ctl_bak\' format \'export/home/backup/L0_%d_CTL_%s.bak\' current controlfile;
        }
        crosscheck backup;
        #crosscheck archivelog all;

        delete noprompt expired backup;
        delete noprompt obsolete;

        list backup;

        exit;
EOF
;;
esac

這是什么原因？請(qǐng)各位高手指點(diǎn)
