Linux Shell Scripting Cookbook - Third Edition

How to do it...

Let's write a simple awk script enclosed in single quotes or double quotes:

    awk 'BEGIN { statements } { statements } END { end statements }'

Or:

    awk "BEGIN { statements } { statements } END { end statements }"

This command will report the number of lines in a file:

    $ awk 'BEGIN { i=0 } { i++ } END{ print i}' filename

Or:

    $ awk "BEGIN { i=0 } { i++ } END{ print i }" filename
