• KXStudio is a collection of applications, artwork and plugins, targeted at audio and video production. KXStudio also provides a Linux Distribution, currently based on Ubuntu 12.04.1 LTS. Although focused on GNU/Linux, some of our applications work in other Operating Systems. (http://kxstudio.sourceforge.net/)

• I was looking for a way to show a map of my local network in my Conky monitor. I came up with the following line for the .conkyrc file:

  • ${texeci 300 nmap -sn 192.168.99.0/24 | grep ‘192.168.99’ | cut -b 22-}

• It’s a simple use of nmap, grep, and cut as “external” commands:

  • ${ … } is conky’s way of identifying a command and its arguments

  • texeci 300 tells conky to run a command in a separate thread every 300 sec

  • nmap -sn 192.168.99.0/24 is the nmap command to do a “ping scan” of one segment of my local network (CIDR Notation)

  • grep ‘192.168.99’ pulls out any line containing the string ‘192.168.99’

  • cut -b 22- grabs the characters (bytes) on the line from the 22nd to EOL
