Description
sed & awk describes two text processing programs that are mainstays of the UNIX programmer's toolbox.sed is a "stream editor" for editing streams of text that might be too large to edit as a single file, or that might be generated on the fly as part of a larger data processing step. The most common operation done with sed is substitution, replacing one block of text with another.awk is a complete programming language. Unlike many conventional languages, awk is "data driven" -- you specify what kind of data you are interested in and the operations to be performed when that data is found. awk does many things for you, including automatically opening and closing data files, reading records, breaking the records up into fields, and counting the records. While awk provides the features of most conventional programming languages, it also includes some unconventional features, such as extended regular expression matching and associative arrays. sed & awk describes both programs in detail and includes a chapter of example sed and awk scripts.This edition covers features of sed and awk that are mandated by the POSIX standard. This most notably affects awk, where POSIX standardized a new variable, CONVFMT, and new functions, toupper() and tolower(). The CONVFMT variable specifies the conversion format to use when converting numbers to strings (awk used to use OFMT for this purpose). The toupper() and tolower() functions each take a (presumably mixed case) string argument and return a new version of the string with all letters translated to the corresponding case.In addition, this edition covers GNU sed, newly available since the first edition. It also updates the first edition coverage of Bell Labs nawk and GNU awk (gawk), covers mawk, an additional freely available implementation of awk, and briefly discusses three commercial versions of awk, MKS awk, Thompson Automation awk (tawk), and Videosoft (VSAwk).
Let's be real: 2020 has been a nightmare. Between the political unrest and novel coronavirus (COVID-19) pandemic, it's difficult to look back on the year and find something, anything, that was a potential bright spot in an otherwise turbulent trip around the sun. Luckily, there were a few bright spots: namely, some of the excellent works of military history and analysis, fiction and non-fiction, novels and graphic novels that we've absorbed over the last year.
Here's a brief list of some of the best books we read here at Task & Purpose in the last year. Have a recommendation of your own? Send an email to ja...@taskandpurpose.Com and we'll include it in a future story.
Missionaries by Phil Klay
I loved Phil Klay’s first book, Redeployment (which won the National Book Award), so Missionaries was high on my list of must-reads when it came out in October. It took Klay six years to research and write the book, which follows four characters in Colombia who come together in the shadow of our post-9/11 wars. As Klay’s prophetic novel shows, the machinery of technology, drones, and targeted killings that was built on the Middle East battlefield will continue to grow in far-flung lands that rarely garner headlines.
