Question

我有一个包含以下数据的File_1.txt。

1234
2567

第二个文件File_2.txt中包含以下数据。

2015-10-30,1234,zxcfgdk,kyfz
2015-10-30,2567,askjfkj,aaaa
2015-10-30,8888,bsjfjah,iojk

我想将File_1.txt数据与File_2.txt的column2数据进行比较。如果匹配，则将整个File_2.txt行重定向到单独的文件。而那些与其他文件不匹配的那个。

用Google搜索了很多页面。但没有任何帮助。

谢谢！

Answer 1

使用TimerElapsedHandler handler=function; ThreadPoolTimer.CreatePeriodicTimer(handler, TimeSpan.FromSeconds(30)); async private void function(ThreadPoolTimer timer) { URL_log_string = device_id_string + "," + UTCdatetime + "," + lng + "," + lat + "," + speed + "," + heading + "," + alt + "," + "," + battery_level + "," + accuracy + "," + 1 + "," + "," + 0; //Locally log storage Log_Class_Object.Save_Data_in_Log("Panic Sent ", URL_log_string); URL_log_string = ""; }：

awk

使用$ cat s.awk BEGIN { FS="," } NR==FNR { a[$1]; next } $2 in a { print > "matched.txt" } !($2 in a) { print > "missing.txt" } $ awk -f s.awk f1 f2 $ cat missing.txt 2015-10-30,8888,bsjfjah,iojk $ cat matched.txt 2015-10-30,1234,zxcfgdk,kyfz 2015-10-30,2567,askjfkj,aaaa：

另一种可能性就是使用grep，但是你需要确保file1中的值永远不会出现在field2之外的file2中（字分隔）：

grep

比较两个不同文件中的非连续字段
