巴什 - while循環在一個文件中，並停止條件

Question

我想讀從/ proc文件一個特定的值，目前是在一個「而讀行」循環中完成，作爲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" 

就這樣，我想進一步改善循環，這樣我可以做的if語句裏面的for循環返回大於0 的值所以停止條件應該是多少次像數：

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

當發生這種情況時，循環應停止並顯示一條消息。

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"
