grep lines between spaces in a file.

[SDCSA]

Hi,

I would like to take a file, grep blocks of lines between spaces and spool them to a different file . Suppose that the file name is a.txt, I'd like to create a1.txt, a2.txt depending on the number of text blocks between spaces. Will appreciate if anyone can suggest me how to do this.

aaaaaaa
aaaaaaa

bbbbbb
bbbbbb

Thanks.

What have you tried so far and where in your code are you stuck ?
Tip: man awk

Hope This Helps, PH.

Hi

Do you have [tt]csplit[/tt] ?

csplit -f 'a' -b '%d.txt' a.txt '/^$/+1' '{*}'

feherke, which *nix has a csplit admitting the -b option ?
Well, GNU csplit admits it, I guess.

Hi

Oops, indeed, the SUS not specifies [tt]-b[/tt]. So it is GNU extension.
Missed that. Thanks.

So, here a legacy portable approach:

awk 'BEGIN{a=1}NF{print >("a"a".txt");next}{close("a"a++".txt")}' a.txt

Hope This Helps, PH.
