Awk splitting one file into n files each one with its header

Question

I am having a hardtime trying to learn how to have 2 output files based on the header and if its possible named with info from the header...

Example original file:

AAABBB12042018

 Jon238444kdhsljdjd7

 Math37378338kdjdkske

AAABBB14042018

 Ash81272722mddnd

 Jay81727272msnsms

1st file named based on header: file-12042018

Jon238444kdhsljdjd

Math37378338kdjdkske

2nd file named based on header: file-14042018

Ash81272722mddnd

Jay81727272msnsms

I dont mind keeping the header or not, my issue is how to handle multiple output names based on a string within the header

is the "AAABBB" part constant? How do we know that it's the header? Is it the lack of leading spaces? — glenn jackman, Apr 24 '18 at 19:43
Gleen its a costant it means its the header exactly that string — Tauan Faria, Apr 24 '18 at 19:49

0

this should do...

$ awk '/^AAABBB/{sub(/^AAABBB/,"file-"); fn=$0; next} {print > fn}' file

if the line starts with this token, replace it with file prefix and print lines to that file.
