Give your sysadmin a hug

A virtual hug of respect to all members of the noble profession on SysAdmin day.

The multitude of skills I needed to develop as a Systems Administrator, even though 15 years ago, are still essential to the job I do today.

When I visit a customer in a crisis, the Systems Administrator is typically the calmest, have the best grasp of the underlying problem and best placed to bring the various parties involved together.

So go on, hug your systems administrator. A systems administrator is for life not just for the 31st of July.

What the quot

One of the joy's of UNIX is that even after 16 years of using it, the opportunity to trip over new useful/interesting commands/features which have been around for a while. Even better if you find something when you are not looking for it.

NAME
     quot - summarize file system ownership

SYNOPSIS
     quot [-acfhnv] filesystem...

     quot -a [-cfhnv]

DESCRIPTION
     quot displays the number of blocks (1024 bytes) in the named
     filesystem (one or more) currently owned by each user. There
     is a limit of 2048 blocks. Files larger than  this  will  be
     counted as a 2048 block file, but the total block count will
     be correct.

This is the output from a root filesystem on a V890 with Solaris 10. The -v option is interesting in that it gives 3 extra columns of blocks not accessed in 30, 60 and 90 days. Yet to think of a use for the -v, but I am sure we will find one.
