vim magic

So I have a bunch of sequences in fasta format - and I need to rearrange the mo'fos.

To start with the entries look like this:

>F13C5.1        CE19383 WBGene00017422  status:Partially_confirmed      UniProt:O76564  protein_id:AAC64611.1

Run this vim command:

:%s:>\(\S\{4,}\)\t.*UniProt\:\(\S\{6,}\).*$:>\1_CAEEL__\2:g

And now they look like this:

>geneName_OrgID__UniProtAccNo
