用命令行拆分大型csv文件

Question

I know OSX supports the linux-like split command.

I have a huge file file.csv

When I run

split -l 1000 file.csv new_

I get created one file new_aa but this file is the same as file.csv , it is not split.

EDIT : when I run file file.csv, I get ASCII text, with CR line terminators . Btw, running wc -l command shows that file.csv has 0 line

Answer 1

Your command is just fine:

split -l 1000 file.csv new_

However, it seems that you have some encoding problems. When you say file file.csv you get

ASCII text, with CR line terminators

So what you need is to port this file from MAC to UNIX. And this can be done with either of these:

mac2unix file.csv
dos2unix -c mac file.csv
