Yet another log analyzer for Squid proxy server. I’ve wrote this one around 2001, but it should still work.
Category: Technology
I work in technology sector. And I do round a clock, not only from 9 to 5. It is my bread and butter, it is my hobby, it is the fascination of my life. And with the current rate of change particular in information technology (IT), there is always something new to learn, to try, to talk about. I often post news, thoughts, and reviews. And when I do, this is the category I use.
userspace.pl
I’ve wrote this script back in 2000, when I was working for J.F.Services Ltd. I needed regular summary reports for disk usage by different users. It is similar to reports sent by repquote. The only reason I used my own script is that I didn’t have any quotas set up at that time.
Backup software
Being a system administrator part of my job deals with backing up and restoring things. In order to find the best tool for the job, I’ve played with a number of solutions. Here is a list of programs that I remember together with some pros and cons for each one.

PHP, Zope/Python, and Perl
There is an article at kuro5hin.net called “Switching from PHP to Zope/Python“. This should provide for an interesting read for all those poor PHP souls.
As for me – I use Perl and I am not planning to change any time soon. There are two major bonuses in Perl for my programming tasks:
- CPAN – Comprehensive Perl Archive Network. This is a huge collection of modules that help me to avoid as much programming as possible. And that’s pretty much.
- Perl’s scalability to all sorts of tasks. I am using Perl for one-line long utility scripts, log analyzing, mail searching, graph building, database maintenance, web programming and anything else that pops up. The broadness of tasks makes PHP way underpowered and Java way too complex. There are tools that might come handy (like Python), but why change if Perl works for me?
Said that, I am familiar with other languages, since it’s not rare at all that I need to patch someone else’s code. PHP being a widely used language for web development comes to my hands pretty often. My Python familiarity is more on the system level and GUI programming.
How can I see a list of all installed RPMs on my system?
“rpm listing installed rpms”
“list all installed rpms”
“list installed packages rpm”
Viewing a list of all installed RPMs on a system is as simple as typing in rpm -qa . Most probably, you’ll want to see the resulting list alphabetically sorted. You can do that by typing rpm -qa | sort into your terminal.
