Hi:

perl -e 'print "hello world!\n"'

A simple filter:

perl -ne 'print if /REGEX/'

Filter out blank lines (in place):

start new:

tmux

start new with session name:

tmux new -s myname

(C-x means ctrl+x, M-x means alt+x)

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

	Almost all of the questions posted in this sub are some form of "what do I have to know/do to pass a tech interview/get a job." Here's some distilled advice I can offer from having conducted over 1000 tech interviews. This doesn't cover everything, but I think it covers the most important foundational elements.

	Setting expectations: If this is your first time looking for a job, or you haven't had to interview in a number of years, expect to invest some effort in preparing for the interview. It's usually the industry professionals that completely ignore this step, but some college students do as well. You're essentially studying for a test, don't slack off - it's going to be work. All of those things that you've been telling yourself don't matter (maybe you're a bit fuzzy on how exactly the internet works - do you really know what happens after you hit enter on the URL bar?) that you don't know - now it's time to address those gaps head on.
