This is part of a long-running series called "google your own title".

There are so many good links I can't even choose one.

'sed' would be great. I recommend it.

Try something. If you get stuck, or get an error - post the output and error message.

See this post, for example:

A: Create list of sequences present in multiple FASTA files

See the right panel, there are usually a lot of similar question-answers there.

OR press "LATEST" button at the left upper corner, type some key-words there - it may halp. In you case:

rename fasta file or something similar,

If you know a bit of python you can give a try to Biopython SeqIO module.

Dear colleague,

I will recommend you to try SEDA. The "Rename header" option (explained in section 3.8 of the user manual) allows you to do exactly what you need.

With best regards,

Hugo.
