I have 2 text files like

________________________________

Company Name:yada yada
ADDRESS:some where, CITY,STATE
CONTACT PEOPLE:first_name1.last_name1,first_name2.last_name2,first_name3.last_name3
LEAD:first_name.last_name
________________________________
&

Data file2
______________________________
COMPANY NAME1:first_name.last_name, first_name1.last_name1,first_name2.last_name2,first_name3.last_name3
COMPANY NAME2:first_name4.last_name4, first_name5.last_name6,first_name7.last_name7,first_name8.last_name8


____________________________


I need to validate people(Bold) in

CONTACT PEOPLE:first_name1.last_name1,first_name2.last_name2,first_name3.last_name3
LEAD:first_name.last_name

against datafile 2 and make sure names in both files match.
(We can assume no name repetitions in data file2 )

i,e. .. I need to grep for each name in file1 against file2

Thank you all for your time

If you are just wanting to see if all the names liste in the first file are present in the second one:

for name in `egrep '^(CONTACT PEOPLE:|LEAD:) datafile1 | cut -d ':' -f 2 | sed 's/,/ /g'`
do
  if grep $name datafile2 > /dev/null
  then
    echo "$name validated"
  else
    echo "$name NOT VALIDATED"
  fi
done
