Topic: The magnificent 'Did you know?' thread

Inspired by Fight Club, a nice film I haven't seen in years...

http://www.abload.de/img/50236_46121291707_18471e97.jpg

I sometimes discover Linux relevant things I find interesting, useful or otherwise enriching, but I can neither find a thread I can necrobump with my findings, or it is too short. I also don't want a blog (and twitter is too loud for me), I don't have much to say at all.

So, if you like, post your little gems here. It's similar to "bash-one-liners" threads, so no big fancy stuff here that could have it's own thread. Maybe something you already shared in a thread, but you think it's generally useful. It's like twitter sans the suck. Short, precise messages. If you have a question, consider opening a thread, if you expect a longer answer. For comments, please quote only the snippet you want to refer to. I see this thread as an educational game and these are the rules tongue

I shall begin. I will mark my snippets bold, but do as you please.

Did you know?
You can scroll in the terminal output back and forth with Shift+PgUp/PgDwn.

Did you know?
You can colorize your man pages using most.

Did you know?
Depending on your distribution, egrep and grep -e show you different results.

Did you know?
You can give multiple file names to a cli application in one command like this: mkdir -p ~/folder/{one,two,three}.

Did you know?
You can grep/cat/less/more/most almost all files in /proc for system information.


Your turn.

Is it within the rules to ask for a little expansion?

While observing the grep manpage, one can find out that there are two possible regex depths in grep, one with -e and one with -E, while egrep equals grep -E.

Did you know?
Every question that can be answered as a Did you know? is fine, everything longer might be a reason to open a thread, but rules are just rules.

The human brain tries to concatenate patterns, especially when a sentence can be formed using 'that', even if the punctiuation might obfuscate the result.

Re: The magnificent 'Did you know?' thread

How dare you defame the illustrious twitter !!!! D:

DId you know twitter also makes me wanna puke. Where else can you hear what Ashton Kutcher had for lunch. Mmmmm tacos, they were good. Such vital information canna be properly disseminated over any other form of communication I tell you !

My one regret is that I cannot hack twitter and respond to him. With some eloquent and well thought out response. Such as ... WHO GIVES A F**K WHAT YOU HAD FOR LUNCH .... DIE !!!

Errrrr ... did you know I've been awake wayyyy too longgggg apparently and am running on caffeine fumes.
