Recursos2, gentoo-devmeeting and other meetings

jalbertosl — Thu, 24 Aug 2006 22:11:57 +0000

I made a ebuild for Recursos2, now you can emerge (~x86) it easily and follow the instruction in the ebuild (really it must work in any distro).

Recursos2 is a bash script that use several system commands (sed, grep, awk, etc) to extract info about your system (cpu, mem, bandwithd, etc). This info can be reported in “raw” mode (nice to create an rrd database), text mode (nice to email it) and in html mode.

Optionally use rrd and imagemagick to create nice use graphs. It is very flexible and works nice in any arch inclusive in embedded systems.

You can download it here.
A live demo here. (some times is not online)
A exmaple of html report here.

In other Hand we are seachign new dates for a gentoo-devmeeting maybe in Jaunary :)

So meanwhile for spanish public i have a talk about Gentoo in the Barcelona’s LUG (15-17 September) and other gentoo Devs will stay there too.

How to use “localepurge”

jalbertosl — Tue, 27 Dec 2005 13:47:50 +0000

A few users have some problems with app-admin/localepurge so i will xplain how o t use it :)

Actually you can use 2 versions. 0.4 version is considered stable and 0.5 is masked because it add a new feature, the multidir search. Use both by your own risk.

Install it :

# emerge app-admin/localepurge

Configure :

You just need to uncomment the features you want to use, and add the locales you want to keep in your system.

# vi /etc/locale.nopurge

Tip : get a list of locales.

# less /var/cache/localepurge/localelist

Execute localepurge :

# localepurge

You can use a few options in command line:

-help,-h : Help!.

-version : Version.

-debug,-d : Debug.

-nocolor,-nc : Disable color output.

-verbose,-v : Verbose output (recomended).

And some options in the config file:

MANDELETE : Purge man pages too.

SHOWFREEDSPACE : Show freede space.

VERBOSE : Verbose output.

NOCOLOR : Disable color output.

enjoy :)
