split big fasta file to smaller ones and retain their headers [closed]

Question

Hello I have a a big fasta file containing smaller files each with a unique header example:

Ssc10_2_8. I want a simple linux command to help me split the big fasta file into smaller files with their headers on these files. So after splitting I want to get something like this:

> Ssc10_2_8
agcggcctt

and

>Ssc10_2_1
tttggttcc

all in separate files.

Answer 1

Try this awk command

awk '/^>/{file=++n".fasta"} {print > file}' InputFile
