Question

我有一个文本文件

DATA SENT TO : 1
DATA SENT TO : 2
DATA SENT TO : 3
DATA SENT TO : 4
DATA SENT TO : 5
Failed to sent data 
DATA SENT TO : 6
Failed to sent data   
DATA SENT TO : 7
Failed to sent data  
DATA SENT TO : 8
DATA SENT TO : 9
  % SENT    % FAILED    AVG   Time    Time   Time    Current
                       Dload  Upload   Total   Spent    Left  
  0            0           0        0      0      0         0
DATA SENT TO : 10
  % SENT    % FAILED    AVG   Time    Time     Time  Current
                        Dload  Upload   Total   Spent    Left  
  0            0           0        0      0      0         0
DATA SENT TO : 11
  % SENT    % FAILED    AVG   Time    Time     Time  Current
                        Dload  Upload   Total   Spent    Left  
  0            0           0        0      0      0         0
DATA SENT TO : 12
  % SENT    % FAILED    AVG   Time    Time     Time  Current
                        Dload  Upload   Total   Spent    Left  
  0            0           0        0      0      0         0
DATA SENT TO : 13
Failed to sent 
DATA SENT TO : 14
DATA SENT TO : 15

从文本文件中找出需要发送的数据总数。如果我尝试使用：wc -l file.txt，那么它将给出总行数。但这不是准确的计数，因为我需要输出为

DATA SENT TO : 1
DATA SENT TO : 2
DATA SENT TO : 3
DATA SENT TO : 4
DATA SENT TO : 5
DATA SENT TO : 9
DATA SENT TO : 10
DATA SENT TO : 11
DATA SENT TO : 12
DATA SENT TO : 13
DATA SENT TO : 15

如果使用了命令sed -e / Failed / {N; d;}->它将删除匹配的和下一行，但是iam无法删除以下3行

% SENT    % FAILED    AVG   Time    Time     Time  Current
                       Dload  Upload   Total   Spent    Left  
  0            0           0        0      0      0         0

Answer 1

尚不清楚是要输出行还是要计数行数，或者两者兼而有之：

$ awk '/DATA SENT TO/ && !f{print} {f=/Failed to sent/}' file
DATA SENT TO : 1
DATA SENT TO : 2
DATA SENT TO : 3
DATA SENT TO : 4
DATA SENT TO : 5
DATA SENT TO : 9
DATA SENT TO : 10
DATA SENT TO : 11
DATA SENT TO : 12
DATA SENT TO : 13
DATA SENT TO : 15

$ awk '/DATA SENT TO/ && !f{cnt++} {f=/Failed to sent/} END{print cnt+0}' file
11

$ awk '/DATA SENT TO/ && !f{print;cnt++} {f=/Failed to sent/} END{print "Total=" cnt+0}' file
DATA SENT TO : 1
DATA SENT TO : 2
DATA SENT TO : 3
DATA SENT TO : 4
DATA SENT TO : 5
DATA SENT TO : 9
DATA SENT TO : 10
DATA SENT TO : 11
DATA SENT TO : 12
DATA SENT TO : 13
DATA SENT TO : 15
Total=11

Answer 2

使用awk对值求和并减去失败的行：

awk '/DATA SENT TO/{sum++} /Failed to sent/{sum--} END{print sum}' test.txt

Answer 3

这可能对您有用（GNU sed）：

var initialArray = [{"key": "key1", "value": "value1"}, {"key": "key2", "value": "value2"}, ...];

var newArray = initialArray .map(function (el) {
   var obj=new Object;
   obj[el["key"]]=el["value"];
   return(obj);
});

禁止隐式打印。删除sed -n '/^Failed to sent/N;/^DATA/p' file开头的行和下一行。仅打印以Failed to sent开头的行。

要获取此类行的数量，请使用：

DATA

或者：

sed -n '/^Failed to sent/N;/^DATA/p' file | wc -l

删除匹配行和必填行
