Editing One-liner program (section)

===AWK===
The book ''[[The AWK Programming Language]]'' contains 20 examples of ''one-liners'' at the end of the book's first chapter.

Here are the very first of them:
# Print the total number of input lines (like [[wc (Unix)|wc -l]]): <syntaxhighlight lang="awk">END { print NR }</syntaxhighlight>
# Print the tenth input line: <syntaxhighlight lang="awk">NR == 10</syntaxhighlight>
# Print the last field of every input line: <syntaxhighlight lang="awk">{ print $NF }</syntaxhighlight>
