Assuming the "blank lines" you described is fixed, eg "\n\n\n", and also your file is not very big, using Python: >>> f = open("inputfile.txt").read() >>> all = f.split("\n\n\n") >>> i = 1 #counter to name your output files >>> for items in all: ............open(str(i) + ".txt","w").write(items) ............i = i + 1 ... >>> the output files will be 1.txt , 2.txt...etc

I think you want to use the csplit command which splits a file based on regular expressions. Take a look at these links: http://www.computing.net/unix/wwwboard/forum/7415.html http://www.computing.net/unix/wwwboard/forum/7134.html
