比较两个文件和带标记的输出文件

Question

一整天都在工作，就是无法正常工作，我从 diff awk sed 中尝试的代码太多，可以再次记住我尝试过的代码，

所以这是我的问题，我有 2 个文件（file1 和 file2）

File1 :

#4 and a row (2)
+1 hello post (5)
10 Years After (6)
21 & Over (8)
50_50 (1)
Almost Christmas (3)

File2:

#4 and a row (2) http://example.com/post1
+1 hello post (5) http://example.com/post2
Not over yet (3) http://example.com/post12
10 Years After (6) http://example.com/post3
Can get it done (2) http://example.com/post24
21 & Over (8) http://example.com/post9
50_50 (1) http://example.com/post7
hear me loud (5) http://example.com/post258
Almost Christmas (3) http://example.com/post5

我的问题是如何比较这两个文件并像这样生成 File3 输出

#4 and a row (2) http://example.com/post1
+1 hello post (5) http://example.com/post2
----> Not over yet (3) http://example.com/post12
10 Years After (6) http://example.com/post3
----> Can get it done (2) http://example.com/post24
21 & Over (8) http://example.com/post9
50_50 (1 http://example.com/post7
----> hear me loud (5) http://example.com/post258
Almost Christmas (3) http://example.com/post5

----> 表示此文本行不在 file1 中。

我希望我已经解释得足够好，如果可能的话请帮助我，因为我缺乏 linux 的技能，先谢谢你！希望有人能帮我解决这个问题。

awk -v s1="---->" 'FNR==NR{a[[=13=]]=[=13=];next} {val=[=13=];sub(/ http.*/,"",val);printf("%s\n",val in a?[=13=]:s1 OFS [=13=])}' file1 file2

而且效果很好

Answer 1

统一差异化怎么样？例如：

diff -u file1 <(awk 'NF--' file2)

输出：

--- file1   2018-03-26 14:59:49.569347677 +0200
+++ /proc/self/fd/11    2018-03-26 15:01:34.117800718 +0200
@@ -1,6 +1,9 @@

Answer 2

Awk解法：

awk 'NR==FNR{ a[[=10=]]; next }
     { 
         r = [=10=]; m = "";
         sub(/ http:.*/, ""); 
         if ([=10=] in a) delete a[[=10=]]; else m = "----> ";
         print m r 
     }' file1 file2

r = [=13=] - 分配给当前处理记录的变量
m - 旨在成为 marker

输出：

#4 and a row (2) http://example.com/post1
+1 hello post (5) http://example.com/post2
----> Not over yet (3) http://example.com/post12
10 Years After (6) http://example.com/post3
----> Can get it done (2) http://example.com/post24
21 & Over (8) http://example.com/post9
50_50 (1) http://example.com/post7
----> hear me loud (5) http://example.com/post258
Almost Christmas (3) http://example.com/post5

Answer 3

能否请您尝试关注 awk 如果这对您有帮助，请告诉我。

awk -v s1="---->" 'FNR==NR{a[[=10=]]=[=10=];next} {val=[=10=];sub(/ http.*/,"",val);printf("%s\n",val in a?[=10=]:s1 OFS [=10=])}' Input_file1  Input_file2

现在也添加 non-one 线性形式的解决方案。

awk -v s1="---->" '
FNR==NR{ a[[=11=]]=[=11=];next }
{
  val=[=11=];
  sub(/ http.*/,"",val);
  printf("%s\n",val in a?[=11=]:s1 OFS [=11=])
}
'  Input_file1   Input_file2

Answer 4

$ cat tst.awk
NR==FNR {
    keys[[=10=]]
    next
}
{
    key = [=10=]
    sub(/ [^ ]+$/,"",key)
    print (key in keys ? "" : "----> ") [=10=]
}

$ awk -f tst.awk file1 file2
#4 and a row (2) http://example.com/post1
+1 hello post (5) http://example.com/post2
----> Not over yet (3) http://example.com/post12
10 Years After (6) http://example.com/post3
----> Can get it done (2) http://example.com/post24
21 & Over (8) http://example.com/post9
50_50 (1) http://example.com/post7
----> hear me loud (5) http://example.com/post258
Almost Christmas (3) http://example.com/post5

比较两个文件和带标记的输出文件

Compare two files and output file with mark
