Splitting and renaming a file using a word delimiter in Linux

I have a file as follows

File name split.txt

file part alpha
abc
def
hij
file part beta
klm
nop
file part charlie
qrs
tuv
wxy
zzz

The file needs to be delimited on the "file part" line and renamed according to last word in the file part line. i.e. after the split, I should have three files as follows:

File 1 - file name is alpha.txt

abc
def
hij

File 2 - file name is beta.txt

klm
nop

File 3 - file name is charlie.txt

qrs
tuv
wxy
zzz

Thus far, I have managed to split the file using the following command

awk '/file part/{n++}{print >"file" n ".txt"}' split.txt

This results in the file names being file1.txt, file2.txt and file3.txt.

How do I get the file names to be alpha.txt, beta.txt and charlie.txt?

This one-liner should help:

awk '/file part/{fn=$NF ".txt"}{print > fn}' split.txt

The idea is same as your codes, just change the sequence number by the last word in the line as filename.
