執行腳本中的命令時出錯

Question

我正在創建一個腳本來從表中獲取計數，將它存儲在一個文本文件中並觸發一封郵件，讓團隊知道當天表中的計數

   #!/bin/bash

    today=$(date +%d-%m-%Y)

    > /tmp/score_cnt.txt

    FILE="/tmp/score_cnt.txt"

    sqlplus -S user/Pass@service<< EOF
    set heading off;

    spool $FILE
    select count(*) from score_tbl;
    spool off;

    count= cat /tmp/score_cnt.txt

    if ($count eq O)
    then (
    echo "Dear All,

    URGENT! Please check if the ETL execution is success as the todays count in Table is 0
    ") | mailx -S smtp=XX:XX:XX:XX:XX -s "COUNT FOR $today : $count" -a /tmp/score_cnt.txt abc@gmail.com

    else

    echo "Today's count in table is $count!"
    | mailx -S smtp=XX:XX:XX:XX:XX -s "COUNT FOR $today : $count" -a /tmp/score_cnt.txt abc@gmail.com

    exit;
    EOF

但是我面臨以下問題，因為有些語句沒有執行。 有人可以讓我知道腳本中有什么問題。

++ date +%d-%m-%Y
+ today=14-03-2020
+ FILE=/tmp/score_cnt.txt
+ sqlplus -S user/Pass@service<< EOF

嘗試：

#!/bin/bash

today=$(date +%d-%m-%Y)

> /tmp/score_cnt.txt

FILE="/tmp/score_cnt.txt"

sqlplus -S user/Pass@service<< EOF
set heading off;

spool $FILE
select count(*) from score_tbl;
spool off;

EOF

count=$(cat /tmp/score_cnt.txt)

if ((count == O)); then
    echo "Dear All,

URGENT! Please check if the ETL execution is success as the todays count in Table is 0
" |
    mailx -S smtp=XX:XX:XX:XX:XX -s "COUNT FOR $today : $count" -a /tmp/score_cnt.txt abc@gmail.com

else

    echo "Today's count in table is $count!" |
    mailx -S smtp=XX:XX:XX:XX:XX -s "COUNT FOR $today : $count" -a /tmp/score_cnt.txt abc@gmail.com

fi

但我想你可以：

count=$(sqlplus -S user/pass@server <<EOF
set heading off;
select count(*) from score_tbl;
EOF
)
