Using Vim as a word processor

March 5, 2013August 31, 2015 Josh Reichardt 64 Comments

Recently I have been asked to share some of my content on a site called Ops School, a very cool site, that bills itself as “a comprehensive program that will help you learn to be an operations engineer”. It is essentially an online guide covering topics geared towards a successful career in IT. If you haven’t checked the site out already I highly suggest you go take a look! Like right now. Even better if you have something to contribute! Either join the mailing list or get going by joining the community over on github. Contributing to this project is a fantastic way to get your name on an Open Source project and would also be a great learning experience if that type of things is interesting to you. At least it has been for me so far.

Anyway, the project has a set of guidelines and styles posted on their site for authors to adhere by. Thus far I have found Vim to be the best word processor for following these styles and also the best way to submit writing to this project, plus it is a good way to force myself to make use of Vim because I don’t get much practice using it otherwise.

I have taken bits and pieces from various other vimrc’s I’ve found and fit them into my own unique scenario, which I suggest you do as well. But the following section is a great example to use a starting point for adding in the word processor functionality to your vimrc.

func! WordProcessorMode()
  setlocal formatoptions=t1
  setlocal textwidth=80
  map j gj
  map k gk
  setlocal smartindent
  setlocal spell spelllang=en_us
  setlocal noexpandtab
endfu
com! WP call WordProcessorMode()

One gotcha that I encountered with this setup initially was that lines didn’t automatically re-balance for me if I went back to a previous paragraph and made a change that caused a line to spill over the 80 character word wrap limit. To do align paragraphs, select the text that has come out of line and type “gq” to balance out the text in the paragraph again.

If you have question let me know. Otherwise, if you have any other tricks or tips that you like to use to enhance your Vim word processing experience feel free to let me know!

Protip March: Quickly viewing logs with Powershell

March 4, 2013August 31, 2015 Josh Reichardt 1 Comment

Wow it feels like it’s been forever since I have posted. I have been crazy busy with work stuff and am just now getting caught up with everything and have enough room to poke my head above the water and breath again finally. We had a massive overhaul of our data center in mid February (among other things) and I am finally getting all the loose ends tied up from that project, including our brand-spanking new test environment which I am super excited about and which I will post about in the not so distant future.

Here is proof of some of our efforts just in case you don’t believe me 🙂

Anyway, getting back on track, I just discovered a slick way in Powershell to mimic the functionality of tail and tail -f in the Linux world. If you have ever used tail then you know it is a great tool for monitoring log files or quickly looking at the end of a piece of code for example.

With the trick I’m about to show you, the same can essentially be done in Windows. However, there are a few caveats. For one, the syntax is a little bit different (if you want to change this just set up an alias). The Powershell equivalent relies on the Get-Content cmdlet with the -Tail and -Wait flags to accomplish this task.

So in the following example I have instructed Powershell to look at the last 30 lines of the uploadpic.ps1 file and using the -Wait flag it will be updated as the file gets appended to.

Get-Content -path .\uploadpic.ps1 -Tail 30 -Wait

If you don’t care about viewing the file live then you can remove the -Wait flag and Powershell will simply grab the last N number of lines where N is 30 in our example. 30 seems like a good enough number in our example and can obviously be changed depending on your needs. Easy enough for what I need it for.

Get-Content -path .\uploadpic.ps1 -Tail 30

As I mentioned, I will be going into a little more detail about some of the things I learned from our data center rebuild that I feel were some great lessons and good things to know/be aware of. Standby for new contents as I get back to writing more blog posts and getting back up to speed on the writing side of things.

Using Find-String to grep in Powershell

January 31, 2013August 31, 2015 Josh Reichardt 7 Comments

For the longest time I have not been a fan of embracing the shell in the Windows world, but more and more I find that Powershell is able to do the things that I need. I suppose my seething hatred was in part due to my negative bias towards Windows and the lack of useful tools from the command line in Windows. Increasingly lately, I have been changing the way I think about and utilize the command line in Windows with Powershell. And to be honest, I’m really beginning to fall in love with Powershell the more I get work with it and the more I get to see how to apply it in Windows based environments. The good news is that Microsoft has put a lot of effort into this and are adding improvements and features all the time. It still has a long way to go, but I can already see this as an alternative to GUI based administration in the Windows world and finally begin to feel like I can see the promise land on the horizon. Using Powershell has been somewhat of a paradigm shift (in my opinion anyways) to how to do Windows administration recently and I feel like it will only get stronger and more common in the years to come. So in this post I will try to show you some of the flexibility as well as some of the power that Powershell has to offer with some great tools from the community.

To highlight what I am talking about, let’s talk about grep, a well known and loved tool in the *nix universe. I love grep. For the longest time, I hadn’t known of a way to grep in the Windows world until just recently with a wonderful third party Powershell module called Find-String. There are a few commands that you need to get this working. To start, we need to get a module installed that is basically used for package management. This tool is called PsGet. Installation is super simple, just run the following from a Powershell prompt, and ensure that your execution policy is set at least at remotesigned (Set-ExecutionPolicy RemoteSigned if you don’t have this turned on).

(new-object Net.WebClient).DownloadString(“http://psget.net/GetPsGet.ps1“) | iex

This should go out, download and install PsGet for you. Once all that has completed you should be able to install Powershell modules that are contained in the PsGet repository. With this installed we can just reach out to the PsGet repo and install our module.

Install-Module Find-String

Easy, simple, and clean. That is the best part, there isn’t a ton of leg work to get this stuff working correctly and is why I’m enjoying Powershell so much these days. Now we have a very functional grep clone! Usage is quite a bit similar to grep, fore help you can do a Get-Help Find-String or look at the link I posted earlier to the author’s github page. If you want to look for a word or substring in a file just use something like this:

Find-String word example.txt

This will output all occurrences of the word you are looking for in the file example.txt. Here is a screen shot to show you.

What other cool Powershell stuff are you doing? I would love to hear about other cool uses that can be beneficial in every day use.

More tips for improvement

January 10, 2013August 31, 2015 Josh Reichardt 10 Comments

The previous post I wrote about becoming a better sysadmin, covering general points and tips for self improvement turned out to be more popular than I thought it would be (okay not really, but for me it was at least!). So I decided to write a little bit of a follow up post in regards to general improvement and subsequently have decided to focus more of my time and effort on including more posts related to that type of content. I find the topic of self improvement to be interesting and would love to write more about my findings, so I will be experimenting a little bit with these less technical pieces a little bit more I think. I would also like to hear what others have to say about these posts and the topic of self improvement so let me know.

While this post is primarily focused on self improvement this can easily be adopted to anybody in the IT industry that is just looking for a way to improve themselves and get better. So while the hard skills (certifications, books, blogs, anything that specifically relates to a specific area) are incredibly important, why not throw in these general and well known strategies to help with your improvement? I think the positive benefits will heavily outweigh the negatives in this scenario.

General Tips for improvement

These simple tips can go a really long way. I read threads all the time about how to get better and how to improve mental capacity, blah blah blah and the following suggestions always seem to pop up. What I have found to be true is that there is no magical instant way to improve yourself, I am learning that the hard way. To me, the best way to see results and really work on yourself starts by changing your habits, working hard and being consistent. That might not be what you are looking for, but trust me, these small tips can go a long way in becoming better at what you do.

Exercise – Time and again I hear and read about the massive benefits of proper exercise. I did not take this advice seriously until just recently and can say that it has made a huge difference in the way I think and the way I feel. I used to always feel beat down and terrible after work until I started exercising so those times of the day where you feel a lot slower are lessened. I wouldn’t recommend starting out by completely changing the way you live your life. Something simple to start with. This summer I started running again, I made a routine out of going out for a run after work, and just kept at it until I started seeing changes. I gradually increased the period of time and distance of my runs, then I added in weight lifting and other types of exercises gradually. By no means am I a hardcore athlete now but I do believe in the importance and benefits of exercising and working your body regularly to improve your mind.

Sleep – This is probably the most important thing to remember when you are trying to work on hacking your mind and improving yourself. 8 hours of sleep seems to be the general rule of thumb, and it should not be overlooked when you are evaluating yourself and your goals for getting to where you want to be. If you want to wake up early, you need to go to sleep early, it really is as simple as that. It is also important to be consistent on your sleep schedule so your body can get used to when it should slow down and when it should speed up (even on weekends!). For example, getting in a routine of winding down at a certain time, say 9 pm every night by reading a book for an hour to train your body that it is time to sleep. Read until say 10 pm every night if you want to wake up at 6 am to get the sleep consistency your body needs, also giving your body enough time to repair and heal itself to get up and going.

Diet – Also important. I realize that everybody is different and I don’t want to speak as if an authority on the subject so please take this advice at face value. The point I want to make though is that diet isvery important in improvement. Again, I do not want to encourage anybody to go all out and completely change every eating habit they have at once. You will crash and burn like many others, it make work for some but generally you will be safer and more likely to make an impact if you take things slowly. Work on one thing at a time and gradually make the changes to improve your diet and health. As an example, start by cutting out something small, like cutting out a particular type of food that isn’t exactly healthy. For me it was soda, and once I had that under control I was able to cut out (for the most part) fast food, etc. Not entirely, I wouldn’t advocate that but cutting back is a good first step. Basically doing something is better than doing nothing.

Protip January: Get your external IP from the command line

January 2, 2013August 31, 2015 Josh Reichardt 10 Comments

Ever need to grab your IP quick but don’t want to get out of the command line or stop whatever you’re working on? Or how about if you have SSH’d into a number of different servers and you simply want to know where you are at currently? This little trick enables you to quickly determine your public IP address without leaving the command line.

I’ll admit, I didn’t originally come up with this one, but liked it so much that I decided to write a quick post about it because I thought it was so nice and useful. There is a great website called commandlinefu.com where users can post all their slick one liners, which is where I found this one. If you haven’t been there before I highly recommend it, there is some really good stuff over there.

This one is simple yet quite useful, which is what I’m all about. The command uses curl, so if you don’t have that bad boy installed yet you’ll need to go get that quick (Debian based distros).

sudo aptitude install curl

Once that is installed simply run the following:

curl ifconfig.me

And bam! Emeril style. Let that go out and do its thing and you will quickly have your external IP address. I like this method a lot more than having to jump out of the shell and open up a browser then going to a website to get this information. It might not save that much time but to me just knowing how to do this is useful and knowledge is power. Or something.
