所以，基本上，我需要删除LIST 1中不是以LIST 2中的一行开头的每一行。例如，LIST 2的第一行是“2000,4031161”，所以我不想删除“2000,4031161,1,1,1008,1000000”。 LIST 1中的一行是“100100,4000019,1,1,0,600000”，由于LIST 2中没有表示“100100,4000019”的行，我希望删除该行。真正的清单是几万行长。我做了一个真正非常长的正则表达式命令，应该使用搜索和替换为我排序，但后来我发现有2048个字符限制，而且我有兴趣找到一个更好的方法来做到这一点。
答案 0 :(得分：0)
我不知道使用notepad ++但使用gawk for windows你可以这样做：
gawk -F"," 'NR==FNR{l[$0]++; next} {if ($1","$2 in l) print $0 }' file2 file1
第一个块在file2中创建条目列表l，第一个文件在参数中给出（ N umber R ecord == F ile N umber R ecord）并跳到下一条记录。
一旦处理了file2，就会为每一行执行第二个块，因为我们使用,作为字段分隔符，我们将{2}首先搜索为l中的键，并仅在它们＆ ＃39;重新出现在列表中。
awk中的列表是引擎盖下的c哈希值，因此即使对于file2中的大量行，RAM也不应该成为问题。
