How to extract a specific gene sequence from several .ffn and put them in one directory

Question

[babdalhamid]

After performing Prokka on hundreds of strains, I have hundreds of .ffn. I want to extract a specific gene sequence from each .ffn and put the gene sequences in one directory, How can I do that?

Thanks

Extract them how? By name? By sequence?

Please show some sample data. Extracting specific sequences from FASTA files has been covered extensively on the forum before. Check out the "Similar posts" feed to the right of this post.
