one column from output column on awk

Question

Suppose which I have this table:

one two three four
two three four five
three four five six
four five six seven
five six seven eight

so I wrote awk -v word=two '$0 ~ "[^[:alpha:]]" word "[^[:alpha:]]"'from this link to access all lines which have two. and the result is whole of line:

one two three four
two three four five

If I want to find just $3. what I should add for that command?

If I want to search on the internet to find the answer. what do I should search? Or better to say this easy:( question refer to which topic of AWK?

Answer 1

You have to use {print$n} to print the nth word. So in your case it would be {print$3}

The Final command becomes,

awk -v word=two '$0 ~ "[^[:alpha:]]" word "[^[:alpha:]]" {print$3}'

which will give output

three
four
