Quick Linux Box Hardware Overview

Tue 31 Mar 2009

Note to self: here's how to get a quick overview of the hardware on a
linux box:

perl -F"\s*:\s*" -ane "chomp \$F[1];
  print qq/\$F[1] / if \$F[0] =~ m/^(model name|cpu MHz)/;
  print qq/\n/ if \$F[0] eq qq/\n/" /proc/cpuinfo
grep MemTotal /proc/meminfo
grep SwapTotal /proc/meminfo
fdisk -l /dev/[sh]d? 2>/dev/null | grep Disk

Particularly useful if you're auditing a bunch of machines (via an ssh loop or clusterssh or something) and want a quick 5000-foot view of what's there.
