如何在Perl中将文件拆分为给定数量的部分？ （在Unix上）

Question

I have several large files, each of which I want to chunk/split it in to predefined number of parts.

Is there an efficient way to do it in Unix (eg via awk/sed/perl)?

Also each file can have varied number of lines.

File1.txt 20,300,055 lines
File2.txt 10,033,221 lines
etc...

Answer 1

如果只想将每个文件拆分为固定行数或字节数的文件，则可以使用split命令。

Answer 2

I found this . You may need to find the number of parts to be splited it too first.

Answer 3

you can use csplit, which can split by context. Check the man/info page of csplit for more info.
