[BiO BB] Get Swiss-Port ID from protein names

I understand that you have the sequences ?
U could download the Swissprot database as one single file.
Transform this large swissprot file such that there is one line per
entry starting with the ID and containing the entire sequence
like
HSLV_ECOLI MADFSDFFFASFSDFFAFASDAFSD ....
HSLV_BACSY MADYSEFFFASFSDFFGFASDAFSD ....
You may need basic text processing skills using  sed, grep, tr.
Then you can then search in this transformed swissprot file
with  fgrep with the 70 sequences as query to identify the respective entry.
