how to split a file based on content 1

[ls62]

Hi,

I have a file that I want to split into multiple files based upon the content. I want to split the file wherever the line begins with "ISA" as the first 3 characters.

I thought I could use "csplit flat.txt '/^ISA/'", but it doesn't work. Am I missing something or is this the wrong command.

Heres a sample of what my data might look like:

---
ISA*A
ALINE1
ALINE2
ISA-B
BLINE1
BLINE2
ISA^C
CLINE1
---

I should get 3 files

Thanks for any help.

Either this:
csplit -s -k flat.txt '/^ISA/' {99}
Or this:
man awk

Hope This Helps, PH.

PH,

Thanks, that did it. Now that it works I understand that the {99} was needed to cause the regexp to be repeated.

Thanks again!
