Example 1

awk -F ',' '{print $NF}' {{filename}}

To print only rows with columns matching a specific string

awk '$3 == "hello"' file

This will match with, 1 2 hello something but not with, 1 2 world something

Lets assume that you want to print the 1st and 3rd field in one line.

echo "A:B:C:D:E:F:G" | awk -F ':' 'ORS=" " {print $1} {print $3}'

Here ORS stands for, The output record separator, by default its a newline.
