[root@linux~]# cat email.txt | grep -i "To:"
To: <test@example.com>

[root@linux~]# cat email.txt | grep -i "Subject"
Subject: Test
Subject: How are you.

I need to print only test@example.com from To field need to eliminate "< & >" from To field and need to print entire subject after Subject:

It should be

[root@linux~]# cat email.txt | grep -i "To:"
test@example.com

[root@linux~]# cat email.txt | grep -i "Subject"
 Test
 How are you.

for email

cat email.txt | awk -F\< '/To:/{ print $2 }' | td -d '>'

for subject

cat email.txt | awk -F: '/Subject/{ print $2 }' | tr -d '>'

OR using sed:

sed -n 's/^To: <\(.*\)>/\1/p' email.txt
sed -n 's/^Subject: \(.*\)/\1/p' email.txt
4 
awk '{gsub(/[<>]/,x)}sub(/^(To|Subject): /,x)' infile

Also,

$ awk -F: '/To:/ || /Subject:/ {gsub(/^[ ]+|<|>/,"",$2); print $2}' email.txt
test@example.com
Test
How are you.

nawk '(/^To/||/^Subject/){sub(".*"$2,$2)}1' infile

sed 's/^To: //;s/^Subject: //;s/[<>]//g' infile

Thanks for the replies.
But sometimes To field contains email addresses in multiple lines. but following listed commands printing only 1st line. e.g.

To: test@example.com, test1@example.com,
      test2@example.com, test3@example.com,
      test4@example.com,

how to print entire To: field emails.

test@example.com, test1@example.com,
test2@example.com, test3@example.com,
test4@example.com,

Would be helpful posting your file email.txt's contents..

sed '/^Sub.*/,/^$/d;/To: /s///' email.txt
