    at 9:45 your use of awk doesn't have a { print } action within the statement. So is the print action not necessary if you pipe from standard output i.e. print using cat and then pipe into awk?

    The last one on sorting, isn't it easy to pipe the output from awk and use sort -u to eliminate the duplicates

    Can you please explain in detail how the unique query works using awk? I know there are more easy ways of finding the unique value but I appreciate that you have taken the effort to create that query. I just need help with
    1. How exactly that query works?
    2. What is in the "array" variable?
    3. How are the values getting assigned to "array" variable?
    4. How the end part ( {array[$0]: print) works and what is assigned to $0 in array variable?

    so why does the header row get counted when 'Age' is ! 24 ? The expected result should have been 3 according to your data set. I can ignore it with c=-1, but that doesn't explain my question.

    awk 'BEGIN {c=0;}
    $5>=24{c++;}
    END {print "there are: ", c;}' employee.txt
    there are: 4

    A very neat and concise video. thanks for your effort. A suggestion: you can minimize the terminal or keep the prompt on the top of the screen, so that it would be easily visible. most of the time the bottom bar of youtube player is hiding what you are typing.
