OFS和FS为=， 有没有办法根据第1列和第3列搜索唯一的行 然后使用第2列和第4列的详细信息打印该行

Answer 1

需要一段时间来弄清楚你想要什么，但我认为你正在寻找：

awk '!a[$1 $3] {a[$1 $3] = $1","$3","} 
    {a[$1 $3] = a[$1 $3] " " $2 " " $4}
    END {for(i in a) print a[i]}' FS=, input-file

或

awk '{a[$1","$3] = a[$1","$3] " " $2 " " $4}
    END {for(i in a) print i","a[i]}' FS=, input-file

主题有很多变化。
