Thanks Don for this useful script!!!

Hi Rudic,

Was just building on your awk commands three things still i am not able to sort out.

1) How to use this awk command recursively in all subdirectory. as of now i am thinking to utilize find something like below

Code:

find . -name "*.*" -exec /usr/xpg4/bin/awk     '               {sub (/--.*$/,"")}
         {sub('/\/\*/,/\*\//',"")}
         $0 ~ PAT       {print FILENAME}
        ' PAT="insurance_no" {} \;

2) if there is multiple occurence of the insurance_no( outside the comment )for each occurence its resulting filename. To just resolve this i put sort -u after pipe. but any other way in awk itself to limit if first occurence then give file name and come out search for another file

Code:

bash-3.2$ find . -name "test_*" -exec /usr/xpg4/bin/awk     '               {sub (/--.*$/,"")}
>          {sub('/\/\*/,/\*\//',"")}
>          $0 ~ PAT       {print FILENAME}
>         ' PAT="RQST_ID" {} \;
./test_2.txt
./test_2.txt
./test_1.txt
./test_1.txt
./test_1.txt

3) As of my understanding this awk command is literally going inside each file and replacing the commented part and then searching for the pattern. in this way performance will degrade. Can we do this in vice versa way first literally search pattern and then replace commented part and then see if there is still pattern in un-commented part.

INSTR(3)						       MBK UTILITY FUNCTIONS							  INSTR(3)

NAME

       instr - find an occurence of a string in a string, starting at a specified character.

ORIGIN

       This  software  belongs	to  the  ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in
       Paris, France.

       Web : http://asim.lip6.fr/recherche/alliance/

SYNOPSYS

       #include "mut.h"
       char *instr(s, find, from)
       char *s, *find, from;

PARAMETERS

       s		   Pointer to the string to be searched for the pattern

       find		   Pointer to the string to be found, the pattern

       from		   Character to be searched backwards before searching for the pattern

DESCRIPTION

       instr searches the first occurence of the string find in the string s, starting its search at the last occurence of the from  character	in
       the string s.

       If either s or find is NULL, the function returns NULL.	If from is (char)0, the pattern is searched from the begining of s.
       This  quite  exotic behaviour is useful to search the occurence of a name in a string resulting from a flatten, when only a terminal object
       name is to be taken into account.

RETURN VALUES

       instr return NULL either if the pattern find is not present in the searched string s, or if one at least of these two string are NULL.	If
       the pattern is found, a value different from NULL is returned.

EXAMPLE

       #include "mut.h"
       /* check for the pattern 'ck' anywhere in the string */
       #define contains_ck(name)instr(name, "ck", ' ')
       /* check for the pattern 'ck' in the signal name, not instance ones */
       #define isclock(ptsig) instr(getsigname(ptsig), "ck", SEPAR)
