I am having large text file having 1000 abstracts with empty line in between each abstract . I want to split this file into 1000 text files. My file looks like
16503654 Three-dimensional structure of neuropeptide k bound to dodecylphosphocholine micelles. Neuropeptide K (NPK), an N-terminally extended form of neurokinin A (NKA), represents the most potent and longest lasting vasodepressor and cardiomodulatory tachykinin reported thus far.
16504520 Computer-aided analysis of the interactions of glutamine synthetase with its inhibitors. Mechanism of inhibition of glutamine synthetase (EC 6.3.1.2; GS) by phosphinothricin and its analogues was studied in some detail using molecular modeling methods.

Click the Splitter tab and press the Input File button to select a file to split (or select the File Splitter Joiner option from file context menus). Note that file sizes must eclipse one megabyte. Next, press the Output Folder button to choose a folder to save the split files in. Then choose how to split the file.
To split a file into pieces, you simply use the split command. By default, the split command uses a very simple naming scheme. The file chunks will be named xaa, xab, xac, etc., and, presumably, if you break up a file that is sufficiently large, you might even get chunks named xza and xzz.
You can use split and set "NUMBER lines per output file" to 2. Each file would have one text line and one empty line.
split -l 2 file
Something like this:
awk 'NF{print > $1;close($1);}' 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)
