Question

我有一个在Linux上运行的每日进程，它返回一组失败的更新用户，并且需要从大用户csv中删除这些错误行以导入数据库。

我的输出文件包含每个失败用户的USER_ID。我试图创建一个已删除的更新文件。我已经回顾了大量可用的示例，但似乎都没有正常工作。我已经包含了错误文件和用户文件的示例。第一行是标题，应该忽略

我的错误文件：

"USER_ID"
"CA781558"
"LN764767"

我的用户文件：

"USER_ID","FIRSTNAME","LASTNAME","LAST_ACTIVITY","GROUD_UID"
"CA781558","Dani","Roper","2015-07-17 19:47:21","CF93DF0A-BD23AF87D20A"
"BT055163","Alexis","Richardo","2016-04-19 21:23:08","CB71F91E-7E638292ABD5"
"LN764767","Peter","Rajosz","2016-03-18 11:59:29","973C4AD2-63BA12BB91CD"
"TN479717","Jerry","Alindos","2015-06-12 07:37:56","1DA745BA-71CB88AA91EA"

"SG839717","Jerry","Alindos","2015-06-12 07:37:56","1BA746BA-71CB88AA91EA"

预期产出：

"USER_ID","FIRSTNAME","LASTNAME","LAST_ACTIVITY","GROUD_UID"
"BT055163","Alexis","Richardo","2016-04-19 21:23:08","CB71F91E-7E638292ABD5"

你能帮忙吗？提前谢谢

Answer 1

您可以像这样使用awk：

awk -F, 'FNR==NR{del[$1]; next} FNR==1 || !($1 in del)' err.txt file.txt

"USER_ID","FIRSTNAME","LASTNAME","LAST_ACTIVITY","GROUD_UID"
"BT055163","Alexis","Richardo","2016-04-19 21:23:08","CB71F91E-7E638292ABD5"
"TN479717","Jerry","Alindos","2015-06-12 07:37:56","1DA745BA-71CB88AA91EA"
"FR915163","Alexis","Richardo","2016-04-19 21:23:08","DBA8B91E-7A6B8292ABD5"
"GB135767","Peter","Rajosz","2016-03-18 11:59:29","AE3C4AD2-63BA181B91CD"
