So this is the books website:
UNIX and Perl to the Rescue!: A Field Guide for the Life Sciences (and Other Data-rich Pursuits): Dr Keith Bradnam, Ian Korf
And apparently : How good is their Unix & Perl material ( Unix & Perl Primer for Biologists ) ? Good enough to get you a job in bioinformatics!
So armed with that knowledge I try python for biologists, stumble upon Python for Biologists books (Python for Biologists and Advanced Python for Biologists) which is kinda similar enough .. so look at the reviews, the perl book by PhD, this book by a PhD ... seemingly positive reviews ... you probably won't go wrong looking more in depth at reviews of this book and comparing to the reviews for the perl book, comparing the table of contents
So I think thats it :) please check it out and report back (in this thread) your thoughts/experiences
