Using Your Browser From the Command Line

Howdy!

I know it’s been a while since I posted – being selfish with all the new things I’ve been learning. I’m sorry. Today I was reminded in strong terms that sharing and giving are crucial, and without all the good stuff other people are posting on the internet, I wouldn’t know most of what I know today.

I want to talk about starting your browser from the command line, in this case I’m using Firefox on Windows. The terminal I’m using is Powershell.

For a long time, I got into the habit of starting my browser like this:

start firefox

I can open my favourite social media site from the shell like this:

start firefox twitter.com

Note that I didn’t even have to prepend the URL with http(s):// or www! Neat, eh?

Sometimes, when I’m really being lazy and I quickly want to jump to Google and conduct a search on “firefox command line options” from there, I just type

start firefox www.google.com/search?q=firefox+command+line+options

I know that this example is rather contrived, but if you understand the basics of HTTP/HTTPS and query strings, this should be easy to grasp.

Having done this for a while, today I decided to look at the Mozilla Developer Network (MDN) reference to see what Firefox had to offer by way of command line options.

And BOOM I hit a mother lode! So far I have only skimmed over it, but I’m astounded at the possibilities I see – this should really make for good browser automation. I wonder why I never thought of it before now.

If I find anything really useful I promise to share (this time). If you’re interested, have a look at MDN’s Firefox Command Line Options page.

I’m out!

Why you should use the Command Line (a lot…)

My office colleague, “R”, is always on my case: “Ha! I’m always amazed to see you using your command line!” Well, remarks like this, kinda make me feel, geeky, but trust me, I’m no nerd – just some curious cat. It may make one look like they have special powers, but I’m just blessed that the first time I started using (or rather, fooling around) with computers, it was at the command line.

It never did much with it, but that start spared me from the irrational trepidation that many people have towards the console. The only DOS commands I knew back then were CD, DIR, TREE and ROBOCOPY – of which I only used the first three. So, I wasn’t really a user. A few years down the line, atrocious internet connections forced me to do ipconfiging and pinging. But that was it. I’m not a Special One.

I use the command line interface (CLI) nowadays for one simple reason: I’m lazy. Maybe I became lazy since I started doing a lot more programming. Nowadays I work principally from Windows Powershell, which is both a CLI and a scripting environment. It can’t get better than this. But here’s why:

    1. It saves me tons of time: After setting up my Powershell profile, whenever I want to read my Bible, I just type in bible. When I want to log onto my WiFi, I pass the instruction smile, and when I’m done I tell my machine to smileoff. How long did it take me to write the script that enables me to do this? Just a few minutes. How much time is it saving me? Cumulatively, hours!

# Alias: smile/smileoff. Command for controlling my personal Wi-Fi
function Connect-Smile
{
    (netsh wlan connect name='Smile@Maverick')
}
New-Alias -Name smile -Value Connect-Smile

# ----------------------------------------#

function Disconnect-Smile
{
    (netsh wlan disconnect)
}
New-Alias -Name smileoff -Value Disconnect-Smile


  1. I have a lot more control over my computer: As one begins to use the command line more often, one gathers more and more experience on its features and the different possibilities. I know feel much more in control when I’m using the computer and I can customise it a lot more, so that it actually is MY computer. As I pick up one or two scripts (or scripting skills) from the internet and apply them to my system, I can make it bend a lot more to my whims and caprices, and also selectively shut out prying eyes.
  2. I gain more expressivity: I read this blog on this issue and I agree with the author – since I started using the command line, almost exclusively, when interacting with the operating system, the mindless mouse clicking has turned into an actual semblance between me and the computer. For good measure, I included a greeting message in my Profile, so whenever I fire up the program, I get this greeting. Are these the beginnings of AI for me (á la Mark)?

  1. I have less stress after upgrades: I remember the jump I had to make from Windows XP/7 and Windows 8. The difference was so clear and the learning curve quite steep. I recall having to make the same leap from Windows 2000 to XP. Why, oh why, Microsoft??? I upgraded to Windows 10 a few months ago, but guess what? I never had to bother about the new interface. I can count on one hand the number of times I have used the Start Menu. When I first saw it I was like “What the heck?! I will operate from my blue screen, thank you very much.” On a serious note, if you can learn to carry out your most mundane tasks and launch your commonly used programs from the command line, you will save yourself hours or even days and weeks of trying to figure out how to use your PC’s GUI after major operating system upgrades because the CLI stays basically the same. This works across platforms to (in a way); the other day a friend asked me to do something on her Mac and being a Mac-ignoramus, I opened the shell, BASH, and worked from there. She was just staring at me with utter amazement!
  2. I can run many programs and utilities in the same window: I discovered this one only recently and I’m exploring it. Just like I mentioned about ipconfig earlier, I found out that I could run Git and R right there in the CLI. So, when I want to just do a quick commit, I run gitcmd, which I pre-configured in my Powershell Profile to run git-cmd.exe. Alternatively, I could have pointed the Git directory to $PATH (for more information on how to do this in Windows, read this article).

This post is getting too long, sorry. There are other benefits you can discover on your own on the internet. All I am saying to those who are so accustomed to clicking-and-pointing: Learn to use command line, especially if you’re a professional or in any kind of technical field. It will save you a lot of hassle once you get the hang of it.

Cheers.
