First, let's take a look at awk.…We've got a simple data file, called simple data dot TXT.…And we can take a look at it with cat.…I'll write cat, simple underscore data dot TXT.…It's a little table of some totally real data.…What awk is great at, and is commonly used for in scripts,…is pulling out programmatically determined data.…To do this, we write an awk program.…Either, right at the command line,…
