Question

我正在尝试格式化每几个小时生成的日志。下面是示例和我尝试过的代码。请帮助我获取所需的格式。

所需的输出：

"""

我可以使用uniq -c来获得最终计数，但是，我一直坚持用#符号代替中间数字。

sed命令使用s!pattern!replacement!g执行全局搜索和替换。搜索模式/(users|geo|places)/[0-9]+与/users/，/geo/或/places/匹配，后跟一个数字。替换字符串/\1/#将原始单词保留在原处，数字更改为#。

$ awk '/^\[/ {print $3,$4,$6}' test.log |
      sed -r 's!/(users|geo|places)/[0-9]+!/\1/#!g' |
      sort | uniq -c
      1 GET /cgi-bin/try/ 200
      1 GET /hidden/ 404
      1 GET /users/#/geo/ 504
      4 GET /users/#/places/ 202
      1 POST /geo/#/places/#/ 202
      2 POST /hidden/ 404
      1 POST /users/#/places/ 202
      1 PUT /cgi-bin/try/ 200
      3 PUT /geo/#/places/#/ 202
      1 PUT /users/#/geo/ 504

如果您想要给定的确切输出格式，可以使用column将数据对齐为整齐的列。

$ awk '/^\[/ {print $3,$4,$6}' test.log |
      sed -r 's!/(users|geo|places)/[0-9]+!/\1/#!g' |
      sort | uniq -c |
      { echo 'verb uri status count'; awk '{print $2,$3,$4,$1}' } |
      column -t
verb  uri               status  count
GET   /cgi-bin/try/     200     1
GET   /hidden/          404     1
GET   /users/#/geo/     504     1
GET   /users/#/places/  202     4
POST  /geo/#/places/#/  202     1
POST  /hidden/          404     2
POST  /users/#/places/  202     1
PUT   /cgi-bin/try/     200     1
PUT   /geo/#/places/#/  202     3
PUT   /users/#/geo/     504     1
