Following is a same solution with perl. See if it helps
perl -pi -e "s/(start[[:space:]]*)(hello)/\$1 HELLO/" Filename
perl -pi -e "s/^([[:space:]]*)start/\$1BEGIN/" Filename
Cheers

Hello Mr. Hari / ChennaiLug Team,
I need your help in wrting a awk script, here's the scenario
1. Match a string pattern in a file and replace the matched pattern with a
new string in the file itself.
Ex:
somefile.txt (contents of this file is as follows)
==========
start hello # start of the comment
end bye # end of the comment
Output Expected
somefile.txt (contents of this file after execution of the script)
===========
BEGIN hello # start of the comment end bye #
end of the comment
find the string 'start \t' and replace it with BEGIN
===================================================
2. Match a string pattern in a file and replace a string with in the next
field of the matched pattern in the same file
Ex:
somefile.txt (contents of this file is as follows)
==========
start hello # start of the comment
end bye # end of the comment
find the string 'start \t' and replace the following field (hello) ==> with
HELLO
Ouput Expected
somefile.txt (contents of this file after execution of the
script) ==========
start HELLO # start of the comment
end bye # end of the comment
===================================================
Kindly reply on this ASAP
