我有这样一个文件：
FirstName, FamilyName, Address, PhoneNumber
我如何按FamilyName对其进行排序？
最佳答案
如果这是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,请将名字作为平局：
sort -k 2,2 -k 1,1 file.txt
“man sort”的相关选项：
-k, –key=POS1[,POS2]
start a key at POS1, end it at POS2 (origin 1)
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.
-t, –field-separator=SEP
use SEP instead of non-blank to blank transition
