The requestor might want the values to be in shell variables so they be processable afterwards, e.g. to email from the script:
Code:
while read id line
        do email=${line##* }
           name=${line% *}
           echo -e '$id='$id'\n$name='$name'\n$email='$email
        done < file
$id=IN301330/00001
$name=pvavan kumar limited
$email=xyz@ttccpp.com
$id=IN302148/00002
$name=PRECIOUS SECURITIES (P) LTD 
$email=viash@yahoo.co.in
$id=IN300239/00000
etc...
