    ZoneType.sh Version 2.0

    We just started supporting Solaris 10 in our VMware cluster so I had to update my zone type script to detect if the OS is running there. I’m not sure how I feel about depending on the output of ptrdiag since the interface is labeled “unstable”, but it works for now, and I really don’t [...]

    UNIX – Find Files that Changed Within Time Window

In other words, those files that are newer than time “X”, but not newer than time “Y”. There are a number of ways to accomplish this, but [...]

    The Banana Slug is not a Mythical Creature

    OK, so I never actually believed that they were a mythical creature, but it took me so long to actually find one after moving to Santa Cruz that I had great fun telling those who didn’t know better that they were figment of the collective local imagination.

    Script to Determine Solaris 10 Zone Type

    We use a lot of local zones in our Solaris 10 environment.
