It rains pretty regularly, in the shell

By

In a 2-article series here on The Linux Rain last May (part 1 and part2) I described how I used AWK to clean up rainfall data for my home town in Tasmania. The result was a file called rain3 with rainfall totals for each of the 36525 days from 1 January 1916 to 31 December 2015: In this article I…

Tweaking uniq -c

By

I often sort lists on the command line and get the frequencies of listed items with the command chain sort | uniq -c. For example, suppose I have a list of "brown" surnames in a file called demo: OK, so there are 7 Brauns in the list, 3 Brouns, and so on. But notice the indentation of…

By

It's pretty easy to see which fields are empty in the tab-separated table demo (below). The 2nd and 4th field, Col2 and Col4, have no visible characters at all in the rows below the header line: That was simple, but what if the table is huge, with lots of fields and records? Eyeballing for fields…

AWK and a rainfall time series - Part 2

By

In part 1 of this article I showed how I used AWK on the command line to work up daily rainfall data for my home town, Ulverstone in Tasmania. I wasn't ready to analyse the data, because there were quite a few missing-data days. Some were part of accumulated-total series, where the rainfall total…

AWK and a rainfall time series - Part 1

By

AWK is my tool of choice for processing plain-text data, so when I wanted to look closely at daily rainfall data for my home town, I fired up a terminal. In this two-part article I explain how the rainfall data were beaten into shape, mainly with AWK, so I could do my analysis. The commands shown…

BASH a block of bytes

By

I was preparing a slide presentation and wanted to show a block of random 8-bit bytes, like this: Naturally I didn't just type out that block of text on a slide, which would have taken maybe 10 minutes, or copy and modify some byte-text I found online.
