对于下面的文本，我需要计算括号之间的数字在 [10-20] 范围内的行数。
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)
我正在尝试以下命令:
cat log.txt | grep -c "This function's cyclomatic complexity is too high. ([10-20])"
cat log.txt | grep -c "This function's cyclomatic complexity is too high. ([10,11,12,13,14,15,16,17,18,20])"
但是没用。正确的做法是什么？
最佳答案
grep -c "(1[0-9])\|(20)" filename
