Bash - 同时循环在文件中并停止条件

Question

我想从/proc 文件中读取一个特定值，目前这是在"读取行"循环中完成的，作为 scheleton：

while read line
do
    if [[ $line = *MATCHES STRING* ]]; then
        for ((  i=0 ;  i<=$someVAR-1;  i++ ))
        do
          [if statement to check if the specific line is not equal with 0]
          then [whatever]
        done
    fi
done < "/proc/FILE"

有了这个，我想进一步改进循环，以便我可以计算 for 循环中的 if 语句返回大于 0 的值的次数。所以停止条件应该是这样的：

if line matches string then
for loop
do
use a variable to keep count that the conditions has been met 2 times.

发生这种情况时，循环应停止并显示一条消息。

while read line
do
    if [[ $line = *MATCHES STRING* ]]; then
        count=0
        for ((  i=0 ;  i<=$someVAR-1;  i++ ))
        do
            [if statement to check if the specific line is not equal with 0]
            then count=$((count+1))
            fi
        done
        if [[ $count -ge 2 ]]
        then break
        fi
    fi
done < "/proc/FILE"
