Linux shell根据第二列排序文件吗? [英] Linux shell sort file according to the second column?

问题描述

我有一个像这样的文件:

I have a file like this:

FirstName, FamilyName, Address, PhoneNumber

如何按FamilyName排序?

How can I sort it by FamilyName?

推荐答案

如果是UNIX:

sort -k 2 file.txt

您可以使用多个-k标志对多个列进行排序.例如，要按姓氏排序，然后将名字作为平局决胜名单:

You can use multiple -k flags to sort on more than one column. For example, to sort by family name then first name as a tie breaker:

sort -k 2,2 -k 1,1 file.txt

人排序"中的相关选项:

Relevant options from "man sort":

-k，--key = POS1 [，POS2]

在POS1处开始密钥，在POS2处结束密钥(起源1)

-k, --key=POS1[,POS2]

start a key at POS1, end it at POS2 (origin 1)

POS是F [.C] [OPTS]，其中F是字段编号，C是字段中的字符位置. OPTS是一个或多个单字母排序选项，它会覆盖该键的全局排序选项.如果没有给出密钥，则使用整行作为密钥.

POS is F[.C][OPTS], where F is the field number and C the character position in the field. OPTS is one or more single-letter ordering options, which override global ordering options for that key. If no key is given, use the entire line as the key.

使用SEP而不是从空白到空白的过渡

use SEP instead of non-blank to blank transition
