New version of dtools

Today I was released a new version of dtools. Distributed tools, aka dtools is a project written in bash coding to create a suite of programs to allow running different UNIX comamnds parallelly in a list of tagged hosts.

Features

• Fully written in bash, no third party software required (except ssh, obviously).
• Based in module architecture, easy to extend.
• Full integration with ssh.
• Easy to group hosts by tags or search by regular expression.
• Manage of ssh hosts
• Parseable output, but human-readable
• Thinking in system admin, no special development skills required to extend the software.

Short Example

$ dt tag:linux ssh date
okay::dt:ssh:myhostlinux1.domain:Mon Nov 16 23:54:04 CET 2009
okay::dt:ssh:myhostlinux3.domain:Mon Nov 16 23:54:04 CET 2009
okay::dt:ssh:myhostlinux2.domain:Mon Nov 16 23:54:04 CET 2009

As usual, you can download the code from the project page, or if you wish you can download the code via git:

git clone git://git.connectical.com/ajdiaz/dtools

Enjoy!

New htop color scheme

From a couple of weeks I use htop in my work to get a fast view about the system status, htop is an an interactive process viewer for Linux, similar to classic UNIX top, but with some enhancements, for example a more configurable view, the integration with strace and lsof programs and much more.

But (and it’s a big “but” for me) I really dislike the color scheme that use by default. htop comming with five color schemes, but I cannot find any beautifull one (from my personal point of view, of course), so I decided to make a new schema. I called “blueweb” theme (dont’ ask) ;). And here is the result:

htop with blueweb theme

You can download the patch file for the htop source code. And yes, unfortunately you need to patch the code.

Now my htop looks nice 🙂

Enjoy!

comida

comida is a bash script designed to create a FTP (or HTTP, or rsync or…) mirror and maintain the archive synchronized with the source. I design this tool when I was working at the Free Software Office (OSL) in the University of A Corunna, and decided to create a new mirror in Spain which host a lot of free software projects. But, we wanted a single tool to manage all mirrors in the archive, with full integration in our web page (yes, we wanted on-the-fly status page).

You can download the source code from launchpad project page or using bzr version control system:

$ bzr get lp:comida
