在 awk 中使用 printf

Question

我有两个文件 $A 和 $B

$A 包含（运算符各不相同，可能是 =、> 或 !=）基本上我有 awk 命令，因为它应该我只想从失败的 $A 添加行

number1 = 460
number2 = 12
number3 > 5
number4 > 20
number5 != 39
number6 != 0

$B 包含

number1 453
number2 12
number3 7
number4 19
number5 39
number6 4

我有一个 awk 命令可以比较两个文件并告诉我数字是否不匹配

output=`awk '
   {
       getline buf <f2;
       split( buf, a, " " );

       if(  == a[1]  &&  == ">" && +0 > a[2]+0 )
           printf( "%s\n", buf );
       else if(  == a[1]  &&  == "!=" && +0 == a[2]+0 )
           printf( "%s\n", buf );
       else if(  == a[1]  &&  == "=" && +0 != a[2]+0 )
           printf( "%s\n", buf );

   }
' f2="$B" $A`

echo "$output"
number1 453
number4 19
number5 39

我正在尝试获取此输出：

echo "$output"
This is the line that failed: number1 = 460 #coming from $A
This is the correct number: number1 453 #coming from $B

This is the line that failed: number4 > 20 #coming from $A
This is the correct number: number4 19 #coming from $B

This is the line that failed: number5 != 39 #coming from $A
This is the correct number: number5 39 #coming from $B

Answer 1

因为我更喜欢使用 sed 而不是 awk，所以有一些东西：

diff -y file1 file2 |
    sed 's/^\(.*\) = *\([0-9]\+\)[ \o11]\+|[ \o11]\+/ ::  !/p;d'
number1 :: 460 ! = 453

你可以安排：

diff -y file? |
    sed 's/^\(.*\) = *\([0-9]\+\)[ \o11]\+|[ \o11]\+ = *\([0-9]\+\)/This is the line that failed:  =  # coming from file1\nThis is the correct number:  =  # comming from file2/p;d'
This is the line that failed: number1 = 460 # coming from file1
This is the correct number: number1 = 453 # comming from file2

$ cat tst.awk
NR==FNR {
    map[] = +0
    next
}
 in map {
    succ = 0
    if (    ( ( == "=" ) && (map[] == ) ) \
         || ( ( == "!=") && (map[] != ) ) \
         || ( ( == ">" ) && (map[] >  ) ) \
         || ( ( == ">=") && (map[] >= ) ) \
         || ( ( == "<" ) && (map[] <  ) ) \
         || ( ( == "<=") && (map[] <= ) ) \
       ) {
        succ = 1
    }
    if ( !succ ) {
        printf "This is the line that failed: %s #coming from %s\n", [=10=], FILENAME
        printf "This is the correct number: %s %s #coming from %s\n", , map[], ARGV[1]
        print ""
    }
}

$ awk -f tst.awk B A
This is the line that failed: number1 = 460 #coming from A
This is the correct number: number1 453 #coming from B

This is the line that failed: number4 > 20 #coming from A
This is the correct number: number4 19 #coming from B

This is the line that failed: number5 != 39 #coming from A
This is the correct number: number5 39 #coming from B
