== Would Gandhi Use Social Media? ==
 
 
If Gandhi were alive today, would he use social media? He was never anti-technology, or even anti-changing with the times. Quite the opposite, actually. If Internet technologies and social networks were around, he would certainly have embraced them -- but with a conscious mindfulness of their strengths and weaknesses.

Related commands are zcat (aka gzcat) and bzcat, for use with gzipped and bzipped archives, respectively. Very useful for easily reading rotated, compressed logfiles - for example, let's say I'm tracking down some jackass that keeps trying to find a way into my server, and I want to look at one of the older sections of my auth log:

ph34r# bzcat auth.log.0.bz2 | grep Illegal
Oct 19 20:47:47 ph34r sshd[35556]: Illegal user adam from 218.38.28.136
Oct 19 20:47:49 ph34r sshd[35558]: Illegal user alan from 218.38.28.136
Oct 19 20:47:52 ph34r sshd[35560]: Illegal user frank from 218.38.28.136
Oct 19 20:47:54 ph34r sshd[35562]: Illegal user george from 218.38.28.136
Oct 19 20:47:56 ph34r sshd[35564]: Illegal user henry from 218.38.28.136
Oct 19 20:47:59 ph34r sshd[35566]: Illegal user john from 218.38.28.136
Oct 19 20:48:14 ph34r sshd[35578]: Illegal user test from 218.38.28.136

Without having to muck around with multiple steps or temporary files or any of that business, I told my server to load up the bzip archive of the last section of my auth log, decompress it, and send the results to grep so that I'd only see the entries related to "Illegal" users. And voila - I can see that the idiot at the APNIC address 218.38.28.136 is trying a dictionary-style username attack on my server.
