Linux Command Line (43) awk pt1

Показать описание

Link to downloads for this video:

awk is a programming language, not as complete as Perl or C, but it is a programming language.

A typical awk script will start with awk then have a condition, code, then an input file filename.

awk has some built in variables like NF for Number of Fields and NR for number of Records. These variables can be used as a condition for what rows to update or select.

awk can be used to do the same things as grep

By default, awk identifies fields separated by white-space. An input file delimiter can giving to separate fields by something other than white-space. To set fields by specific columns those columns will need to be defined int he variable FIELDWIDTHS.
