Using awk, please write a script called activity5.3-4.awk to print the full name, Email Address, state and zip for those with an “imap” email. Be sure to use multi-line statements for improved readability. Include the header identifying each field, and a footer indicating the end of listing.

Explanation / Answer

>> awk -F "," '{if (match ($2, /' "{@imap}" '/)) {print $1, $2, $4, $5}}' activity5.3-4.awk

-F is used to set the field separator.

"match" is used to find the required substring, here @imap.

After checking, we are printing all the required fields.
