Free Ebook . Being able to export my workflow to a PDF is useful too. 2) The Command Line is.

Expertise in data-intensive languages comes at the price of spending a lot of time on them. In contrast, bash scripting is simple, easy to learn and perfect for mining textual data. I then worked on creating a few tutorials demonstrating four practical flat file data mining projects each with a different objective function: University ranking data, Facebook data, Australian statistics crime data and Shakespeare-era plays and poems data all data were collected from public domain , but mainly at my spare times.

I would say it was fun to see the potentials of command line tools!

How to do Data Science @ command line?

Coming with some backgrounds on Linux-based Supercomputing and parallel data mining, I wanted ensure that my target audience can get going with data on the Linux shell!

He first reads the tutorials and then comes back to the projects after getting some basics on the Bash shell.

The tutorial section introduces him with bash scripting, regular expressions, AWK, sed, grep and so on. I also did not want to publish a print book! Therefore, I approached the leanpub. Leanpub is the combination of two things: a powerful book writing platform, and an online storefront where you can download books.

It took me sometimes to write and format the book in the Markdown format, but I would say it was really an awesome experience. The book became available in several format, as soon as I pressed the Publish button!

Hands-On Data Science with the Command Line

The course was voiced by a voice artist named A. All Rights Reserved.

Remember, the Unix philosophy favours small programs that do one thing and do it well. Assuming that we stored the data from the last step in million. Since CSV is the king of tabular file formats, according to the authors of csvkit , they created, well, csvkit.

Since the publication of this post, json2csv has been updated to print the header with the -p option. Other tools within csvkit that might be of interest are: in2csv, csvgrep, and csvjoin.

And with csvjson, the data can even be converted back to JSON. All in all, csvkit is worth checking out.

Therefore, xml2json is a great liaison between scrape and jq. In that case, sample might be useful. The first purpose of sample is to get a subset of the data by outputting only a certain percentage of the input on a line-by-line basis.

The second purpose is to add some delay to the output. This comes in handy when the input is a constant stream e.

The third purpose is to run only for a certain time. The following invocation illustrates all three purposes.

Moreover, there is a millisecond delay between each line and after five seconds sample will stop entirely. Please note that each argument is optional. In order to prevent unnecessary computation, try to put sample as early as possible in your pipeline the same argument holds for head and tail.

1. jq - sed for JSON

Therefore, as a proof of concept, I put together a bash script called Rio.Raymond Page is a computer engineer specializing in site reliability. It's the end of the world as we know it while and until. Display the five-number-summary of each field. Since CSV is the king of tabular file formats, according to the authors of csvkit , they created, well, csvkit.
