   [["QUALITY","AVM”,100,610865413,1,0,7,2,-1]

这是我的日志。我想要模式如下：

**"AVM",200** - In the above log, how many time this pattern comes. Result should be **3**

我试过了：

**grep "\"AVM\",200" <file> | wc -l** --> but its not giving perfect result

如果每行有一个匹配项，请使用-c选项

grep -c '"AVM",200' log

如果有多个匹配项，则每行打印一个匹配项，然后计算行数（取决于grep实现，而不是全部都有-o选项）

grep -o '"AVM",200' log | wc -l

或使用GNU awk将搜索字符串设置为记录分隔符并使用记录数来计算

awk -v RS='"AVM",200' 'END{print NR-1}' log
# to handle empty input as well
awk -v RS='"AVM",200' 'END{print (NR>1?NR-1:0)}'

或计算每行的出现次数

awk -F'"AVM",200' 'NF{total += NF-1} END{print total+0}' log

如何grep双引号后跟一个字符串同时？
