grep -E ‘404 | 500’ nginx.log

28

find_error_log(){
grep -E ‘( 404 )|( 500 )’ nginx.log
}

29 
find_error_log() {
    awk '{if ($9=="404" || $9=="500") print }' nginx.log
}
30

find_error_log(){
awk -F " " ‘{print $9}’ nginx.log|grep -E ‘404|500’
}

31

cat nginx.log |grep -E ‘" (404|500)’

32

卡在怎么打印出那一行了
awk ‘{print $9}’ nginx.log | grep -E ‘500|404’
这种只打印出了状态码

33

grep -oE ‘^[0-9].[0-9].[0-9]*.[0-9]’ nginx.log | sort | uniq -c | sort -rn | head -3

34

less nginx.log | awk '{print $1}'|sort |uniq -c| sort -nr | head -n 3

35

less nginx.log |awk ‘{print$1}’| sort | uniq -c | sort -nr | head -5

36

less nginx.log | awk '{print $1}' | sort |uniq -c | sort -nr | head -3
