You can use split and set "NUMBER lines per output file" to 2. Each file would have one text line and one empty line.

您可以使用 split 并将“每个输出文件的 NUMBER 行”设置为 2。每个文件将有一个文本行和一个空行。

split -l 2 file

Something like this:

像这样的东西：

awk 'NF{print > ;close();}' file

This will create 1000 files with filename being the abstract number. This awk code writes the records to a file whose name is retrieved from the 1st field($1). This is only done only if the number of fields is more than 0(NF)

这将创建 1000 个文件，文件名是抽象编号。此 awk 代码将记录写入一个文件，该文件的名称是从第一个字段 ($1) 中检索到的。仅当字段数大于 0(NF) 时才这样做

You could always use the csplit command. This is a file splitter but based on a regex.

您始终可以使用 csplit 命令。这是一个文件拆分器，但基于正则表达式。

something along the lines of :

类似的东西：

csplit -ks -f /tmp/files INPUTFILENAMEGOESHERE '/^$/'

It is untested and may need a little tweaking though.

它未经测试，但可能需要稍作调整。
