How do you find all the directories and how do you determine programmatically which of them are empty? But let's look at how this task can be made very easy by taking advantage of the normal behavior of the rmdir command. http://www.itworld.com/it-managementstrategy/67200/recursively-removing-empty-directories#comments IT management/strategy Operating systems How-to find remove empty directories rmdir Sandra Henry-Stocker xargs Wed, 29 Apr 2009 14:53:08 -0400 Sandra Henry-Stocker 67200 at http://www.itworld.com http://www.itworld.com/operating-systems/55321/grappling-disk-space Disks are getting bigger and bigger, but so are our users' data collections.

Let's look at some useful commands. http://www.itworld.com/operating-systems/55321/grappling-disk-space#comments Business intelligence Operating systems How-to disk space find full Sandra Henry-Stocker Wed, 24 Sep 2008 15:30:07 -0400 Sandra Henry-Stocker 55321 at http://www.itworld.com http://www.itworld.com/nlsunixsubnet070515 If you have ever needed to survey a large group of systems to find out which of them supported some particular service, such as ftp, telnet, ssh or some other particular application, you have probably thought of numerous ways to query the systems for the required information and display it in some usable fashion. Many methods of obtaining information from servers, however, require some sort of login or a remote shell request that either takes more time than you want to spend or requires you to configure some sort of trust on the part of the systems with the information for the system on which it is being collected. In today's column, we will look at a way to find out about services running on systems without setting up any access ahead of time. http://www.itworld.com/nlsunixsubnet070515#comments Development Operating systems How-to find nmap Sandra Henry-Stocker services Mon, 14 May 2007 12:23:34 -0400 jnaze 4255 at http://www.itworld.com
