So many books are thick, wordy, and conceal their nuggets of wisdom, but not this one. It's not big, so you won't find full details on (eg) all of the many Linux email clients - but they get a mention.
Works well for me (ex BSD 4.x sysop in the 1980s) as well as friends with no previous knowledge of operating systems. It's the examples that are such a help - most of the things we've needed to do are covered with a brief, relevant example. We use it with Ubuntu mainly - Debian distros are not identical to Fedora but we've not seen a problem - both are Linux and conform to the POSIX standard.
Reading it cover-to-cover is logical, informative, and highly recommended. Three times, and the info is starting to stick..... Then keep it handy to look things up when you need them! Highly recommended.
