By Juliet Kemp

Usually we deal with Apress /No Starch press and particularly O'Reilly books (with these black-white animals on disguise) because the optimum authority in IT. We clearly count on that these books are written via hard-core specialist which could mentor of all. good, that isn't the case with Juliet Kemp booklet "Linux process management recipes" - the entire ebook has the "unwritten notion" - "Hey, cost this out!" . that implies that it has to be regarded as a kind of article in Linux journal that covers a few Linux/sysadmin options that received Julie Kemp mesmerized, yet now not the forged reference material.

For instance, web page. 188

ldapsearch "(uuid=testuser)" | sed '/^#/d' | sed '/^$/d' - good , that works yet any first rate skilled sysadmin will let you know that it's not cool to pipe sed to sed, as a substitute you employ '-e' command -

ldapsearch "(uuid=testuser)" | sed -e '/^#/d' -e '/^$/d' - that's a lot nicer. i'm really not splitting a hair the following, yet IMHO books like this should have extra elegance.

Also the full inspiration of centralization utilizing LDAP /NFS / puppet isn't essentially illustrated during this e-book - a number of Visio / Omnigraph diagrams should be a major support to appreciate the total inspiration and to determine even if it may be utilized in your community. i'm interpreting among the traces that Juliet Kemp has came upon LDAP /NFS /puppet / bash final touch / perl -and she is making an attempt to inform us "See, what i'm using... isn't really it cool or what?"

We want much less "discovery channel", yet extra research right here. it's not that i am telling you that the ebook is dead - it has a few great principles, however the second variation (if Juliet Kemp cares) have to be heavily revised
