extract sequences from a fasta file and save into different files

Question

[Eva_Maria]

Hey I have a fasta file which contains more than 80 sequences. I want to take each sequences in different files and the file name should be header of corresponding sequence.

[Naren]

That's simple but the header should not contain illegal characters for a filename i.e. \ / : * ? " < > |

a simple loop will do that if one takes care of these chars.

[Eva_Maria]

yup header like this only GCF_000196095n.fasta_2 ..
