Being productive is fun.

There are a lot of fields to improve your productivity. Today I am going to share some command line tips and tricks to make your life easier.

TLDR

My full setup includes all the stuff discussed in this article and even more. Check it out: https://github.com/sobolevn/dotfiles

Shell

Using a good, helping, and the stable shell is the key to your command line productivity. While there are many choices, I prefer zsh coupled with oh-my-zsh . It is amazing for several reasons:

Autocomplete nearly everything

Tons of plugins

Really helping and customizable PROMPT

You can follow these steps to install this setup:

Install zsh : https://github.com/robbyrussell/oh-my-zsh/wiki/Installing-ZSH Install oh-my-zsh : http://ohmyz.sh/ Choose plugins that might be useful for you: https://github.com/robbyrussell/oh-my-zsh/wiki/Plugins

You may also want to tweak your settings to turn off case sensitive autocomplete. Or change how your history works.

That's it. You will gain instant +50% productivity. Now hit tab as much as you can!

Theme

Choosing theme is quite important as well since you see it all the time. It has to be functional and pretty. I also prefer minimalistic themes, since it does not contain a lot of visual noise and unused information.

Your theme should show you:

current folder

current branch

current repository status: clean or dirty

error codes if any

I also prefer my theme to have new commands on a new line, so there is enough space to read and write it.

I personally use sobole . It looks pretty awesome. It has two modes.

Light:

And dark:

Get your another +15% boost. And an awesome-looking theme.

Syntax highlighting

For me, it is very important to have enough visual information from my shell to make right decisions. Like "does this command have any typos in its name" or "do I have paired scopes in this command"? And I really make tpyos all the time.

So, zsh-syntax-highlighting was a big finding for me. It comes with reasonable defaults, but you can change anything you want.

These steps brings us extra +5%.

Working with files

I travel inside my directories a lot. Like a lot. And I do all the things there:

navigating back and forwards

listing files and directories

printing files' contents

I prefer to use z to navigate to the folders I have already been to. This tool is awesome. It uses 'frecency' method to turn your .dot TAB into ~/dev/shell/config/.dotfiles . Really nice!

When printing files you want usually to know several things:

file names

permissions

owner

git status of the file

modified date

size in human readable form

You also probably what to show hidden files to show up by default as well. So, I use exa as the replacement for standard ls . Why? Because it has a lot of stuff enabled by default:

To print the file contents I use standard cat or if I want to see to proper syntax highlighting I use a custom alias:

# exa: alias la="exa -abghl --git --color=automatic" # `cat` with beautiful colors. requires: pip install -U Pygments alias c='pygmentize -O style=borland -f console256 -g'

Now you have mastered the navigation. Get your +15% productivity boost.

Searching

When searching in a source code of your applications you don't want to include folders like node_modules or bower_components into your results by default. You also want your search to be fast and smooth.

Here's a good replacement for the built in search methods: the_silver_searcher .

It is written in pure C and uses a lot of smart logic to work fast.

Using ctrl + R for reverse search in history is very useful. But have you ever found yourself in a situation when I can quite remember a command? What if there were a tool that makes this search even greater enabling fuzzy searching and a nice UI?

There is such a tool, actually. It is called fzf :

It can be used to fuzzy-find anything, not just history. But it requires some configuration.

You are now a search ninja with +15% productivity bonus.
