Solaris diskspace calculation in Megabytes
Someone asked me how they can compute the diskspace (used/available) in Megabytes. The goal is to get the info in Megabytes only and report it, so that other programs can make use of it in automation. As a backdrop – the df command in Solaris supports the -k switch, which computes the diskspace in kilobytes.… Continue reading Solaris diskspace calculation in Megabytes

Installed Solaris 2009.06 desktop
Installed Solaris 2009.06 on my personal desktop over the weekend. The installation is nice and smooth. One caution for users who use multi-boot environments: you must backup the menu.lst before you install. Just in case you need to manually edit. Read here. The base OS doesn’t come with many utilities that you would like to… Continue reading Installed Solaris 2009.06 desktop
