Question

对于以下文字，我需要计算括号之间的数字在[10-20]范围内的行。

This function's cyclomatic complexity is too high. (1)
This function's cyclomatic complexity is too high. (2)
This function's cyclomatic complexity is too high. (3)
This function's cyclomatic complexity is too high. (4)
This function's cyclomatic complexity is too high. (5)
This function's cyclomatic complexity is too high. (6)
This function's cyclomatic complexity is too high. (7)
This function's cyclomatic complexity is too high. (8)
This function's cyclomatic complexity is too high. (9)
This function's cyclomatic complexity is too high. (10)
This function's cyclomatic complexity is too high. (12)
This function's cyclomatic complexity is too high. (13)
This function's cyclomatic complexity is too high. (14)
This function's cyclomatic complexity is too high. (15)
This function's cyclomatic complexity is too high. (16)
This function's cyclomatic complexity is too high. (17)

我尝试以下命令：

cat pruebascript.txt | grep -c "This function's cyclomatic complexity is too high. ([10-20])"
cat pruebascript.txt | grep -c "This function's cyclomatic complexity is too high. ([10,11,12,13,14,15,16,17,18,20])"

但没有奏效。这是正确的方法吗？

Answer 1

grep -c "(1[0-9])\|(20)" filename

Answer 2

grep是错误的工具。您不希望使用正则表达式进行数值比较。尝试：

awk "/This function's cyclomatic complexity is too high./"'$2 >= 10 && $2 <=20 {c++} END {print c}' FS='[()]' pruebascript.txt

请注意，您可以简化为：

awk '$2 >= 10 && $2 <=20 {c++} END {print c}' FS='[()]' pruebascript.txt

取决于您的实际数据。

Answer 3

我无法访问终端，因此未经测试，请尝试cat pruebascript.txt | grep -c "This function's cyclomatic complexity is too high. (1[0-9]|20)"。您在grep中的正则表达式要求1或2，以及2或0。

1 [0-9]将匹配10到19之间以及20之间的任何内容。

Answer 4

要列出grep的不同字符串，请将其\(\)包围，并与\|分开，如下所示：

$ grep "This function's cyclomatic complexity is too high. (\(10\|11\|12\))" file
This function's cyclomatic complexity is too high. (10)
This function's cyclomatic complexity is too high. (12)
