Hi Narasimham,

If you only want the first occurance of "phone:" do:

grep "phone:" file | head -1

If "phone:" must be at the beginning of the line use "^phone:".

This is a little bit more complicated if what you really want, is the first 'Phone:' after each 'Name:'. If that is the case, then a little bit of Perl or Awk will be your best bet. Is this what you are really trying to do?

1. With grep, you can also add '-i' for case-insensative searches Phone vs phone

2. To get the first Phone: from each /Record:/

perl -ne '/^Record\s+(\d+)/ and $rn=$1,next;$rn&&/^Phone/i or next;print;$rn=0;' datafile
