AWK&SED oreilly book:

Quote:

Awk, in the usual case, interprets each input line as a record and each word on that line, delimited by
spaces or tabs, as a field. (These defaults can be changed.)

Before text AWK is said that programming language... in that context, what it be if defaults would be changed. What is the special meaning of record or field?

In all language you have at some time have to accept data, do something with it, or write...
Those data can be in files...
And so you learn instructions to read or write...
But when you say read, what do you actually read? A record!
An a record can be 1 or more fields,
How to differentiate the fields? by delimiters...

If you were to speak SQL you would talk of rows and columns...
