Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Needed a quick way to see if my server distro that I setup years ago was running 32bit or not, since with time I had forgotten.

Note: does not check _hardware_ e.g. /proc/cpuinfo but rather the kernel installed

arch
sudo lshw -C cpu|grep width
isainfo -v

This is likely only valid on Solaris based systems. Unfortunately a lot of the more universal techniques for determining if a system is 32bit or 64bit on x86 solaris fail to give much more information than "i86pc"

Know a better way?
