seqret asis::ctgatcgatgctagctgac

the "asis" format was included exactly for this purpose. You do need to 
take care that a long sequence is not too long for your shell to handle 
on the command line (a shell issue, not an EMBOSS issue).

You can also add to the command line:

-sid abc123

This will give it an ID of abc123 and the output file will default to 
(for seqret) abc123.fasta and will have the abc123 identifier in it.

Hope this helps
