Is it true about these tools?
 

Hi guys,

a friend of mine who works for a big company in london sent me an email recently and told me that if i learn the following tools...or at least half of them i would be able to ace any Linux Engineer interview...it is a diagram explaining where the tools fit in. Just thought i would share it with the community, and get some feed back...also...how possible is it to learn and utilise these tools in a non production environment...HA HA!!! looking at the attachment after uploading...it actually looks like the London Underground LOL!!!

That's a great guide! Thanks for that.

Thanks.

I am not clear on what a lot of these tools do so having them all on the one page allows me to read up on them.

Thanks, that is a simple, useful and clear graphic!

As far as "aceing" any Linux Engineer interview, there is a little more involved in that than memorizing a few commands I think!

Well, there are a few new ones for me, and probably others besides! Thanks for sharing. If you work through those, studying the man pages and trying them out, you're obviously going to learn a lot. But there'll be a lot of background reading needed as well. I had to look up slabtop and found that it gives you a real-time display of kernel slab cache information. So, the questions are (1) how do you interpret that display and (2) under what circumstances would you need it? If you can answer questions like that about all those commands, you'll really know your Linux.

Yes, it is. So good, I added a subscription, just so I wouldn't lose it.

thx for sharing the nice pic

most of the tools there are fairly easy to use
strace and latrace will show you exactly what a program calls (strace for kernel calls, latrace for library)
iotop, iptraf, perf will show you performance/io thingies
netstat, ethtool, lsof, pidstat and such will show you the state of things
ptrace is fun :)

id like to add iftop, that i like more then netstat
atop that can show (and log) most of these things
and the /proc and /sys interfaces that can give plenty of useful information (amongst other things)

that is definitely a great guide for beginners, im saving the pic myself too.
