如何匹配如下行

cuuccuuc

大侠们！问下：

bash-3.00$ more 2.txt
networktype = 1 [1:GMS 2:TD]
networktype = 1 [1:GMS 2:TD]
networktype = 2 [1:GMS 2:TD]
networktype = 1 [1:GMS 2:TD]
networktype = 1 [1:GMS 2:TD]

我要匹配加粗这行该如何匹配？
sed -n 3p就算了。。。

假如文件里有几万行，该如何匹配。

谢谢！

grep ‘2 \[1:GMS 2:TD\]‘ 2.txt
networktype = 2 [1:GMS 2:TD]

或者
awk ‘/2 \[1:GMS 2:TD\]/{print $0}’ 2.txt
networktype = 2 [1:GMS 2:TD]

或者用sed
sed -n ‘/2 \[1:GMS 2:TD\]/p’ 2.txt
networktype = 2 [1:GMS 2:TD]

justlooks

grep -P '=(?= 2)'
