You don't give any particular details about which logs you want to analyze or what you're specifically looking for however, a basic understanding of just 4 cli commands will let you quickly, reliably and flexibly handle almost any log file you might desire.
grep | egrep
sort
awk
head | tail | tail -f
I'm sure others can contribute more of their favorite cli hacks however I spend most of my time working with some variation of these four. A basic understanding of them and the structure of the data you're working with will make log analysis a snap (most of the time).
