conditions : if the 2nd column is – then 2nd condition check last column value beginning in 4 then count the Name (William and John) Output :

3 John
2 William

Answer

Try:

awk -F ' ' '{if ($2 == "-" && $NF ~ /^4/) print $3}' <file_name> | uniq -c

Explanation: We are using if statement in awk to check the two conditions:

• If 2nd element is equals to ‘-‘
• If last element begins with 4

If above two conditions are true, we are printing name, stored in 3rd element

uniq -c will count occurrences of the names
