How to run PSSPred on multple sequences

Hello,

I understand to run the script on a fasta file with a single sequence in it, the command is 'perl PSSpred.pl file'.

How do I run it for a fasta file with multiple sequences, in the quickest/most efficient way? (e.g. I understand I can split my file of 1000 sequences into 1,000 files of one sequence each and then run 'for i in .fa ;do perl PSSpred.pl $i ;done'; I'm just wondering if there's a more efficient/quicker way.

Thanks
