Learning Linux | Linux from the command line | Linux for sysadmins
This article combines all three of my most common Linux post categories. It's a great resource for a lot of the tools you'll need to become a polished Linux user.
UPDATE: Yes, this is an old post but the great thing about a well designed system is that it lasts for a long time. Most of these commands and their usage are the same today. In fact most are the same as 25 years ago.
That's why learning them and the *NIX command line is a wise investment in your future as a sysadmin or even as a user. Fancy pretty GUI tools will come and go, but bash is forever.

I remember those. It appears that the hipster kids today, nearly a decade after vivek's post, wouldn't seem to want most of these. Instead, many I know are using prometheus.io - Prometheus - Monitoring system & time series database to record graphable histories from all sorts of devices, involving thousands of parameters per device.
ReplyDeleteAnyways, thanks for the good memories!
Refurio Anachro Yeah, they don't bother learning the basics so as soon as they lose their pretty toys or sit down at a different system they're helpless and useless.
ReplyDeleteSure. But I have to admit that I, too, feel lost with the old stuff. It'd certainly take me way longer to figure out how to use the old tools to plot, say, the correlation between http response time and interrupt load over a cluster. With a time series database I can test many such hypotheses on past data within minutes.
ReplyDeleteSo, monitoring has changed and I'd consider the related tools from the article as outdated. But for debugging and reverse engineering I'd still rely on strace and friends.
I just noticed you amended your post. Maybe I could have prevented us from talking past each other by making more clear where I was heading right away. Apologies for my slightly counterproductive cheekyness! Cheers!
ReplyDeleteRefurio Anachro well you're talking about the wrong tools for the wrong job too.
ReplyDeleteI'm saying "Learn to use a stethoscope to check heart rates" and you're replying "No, I prefer to use an MRI to find brain tumors"
You still need to learn to use a stethoscope.
Maybe. I don't think I'll ever touch sar again, but maybe that's just me. Nevertheless, what an interesting metaphor!
