未在 isql 命令中获取变量的值

Question

下面我尝试自动化 Sybase 报告作业，但无法获取变量值作为 sp_helpdb proc 的参数。

#!/bin/sh

. ./SYBASE.sh

dblist=`isql -S syb157134 -Usa -b -P << endit 
use master
go
set nocount on
go
select name
from sysdatabases
go
exit
endit
`

for db in $dblist
do
        if [ -n "$dblist" ]; then
                `isql -S syb157134 -Usa -b -P <<EOF > /sybase/pankaj/INPUT/sp_helpdb_$db.txt
                use master
                go        
                sp_helpdb "$db"   ------not able to get the $db variable value
                go              
                exit
                endit
                EOF  
                `  

        else
                echo "Array empty"
fi

done

引号中的变量不会在定界文档内展开。您应该删除双引号"$db"
