从文件中读取关联数组

Question

我有一个内容文件:

( [datname]=template1 [datctype]=cs_CZ.utf-8 )
( [datname]=template0 [datctype]=cs_CZ.utf-8 )
( [datname]=postgres [datctype]=cs_CZ.utf-8 )
( [datname]=some\ stupid\ name [datctype]=cs_CZ.utf-8 )
( [datname]=jqerqwer,\ werwer [datctype]=cs_CZ.utf-8 )

我想读取每一行并将上下文推送到关联数组变量.以下代码我没有成功:

(cat <<EOF
( [datname]=template1 [datctype]=cs_CZ.utf-8)
( [datname]=template0 [datctype]=cs_CZ.utf-8 )
EOF                      
) |                      
while read r             
do                       
   declare -A row=("$r") 
   echo ${row[datname]}  
done;

我收到一个错误:

test3.sh: line 8: row: ( [datname]=template1 [datctype]=cs_CZ.utf-8 ): must use subscript when assigning associative array

可以从文件中读取数组吗？

进行以下两项更改:删除declare语句中的括号,并使用read选项-r(禁用转义字符):

while read -r line; do
   declare -A row="$line" 
    ...  
done
