How to ignore single or multiple lines between /* and */ while reading from a file in unix?
I have a file proc.txt:
Code:
if @debug = 1 then
   message 'Start Processing ', @procname, dateformat(now(*), 'hh:mm:ss'), @julian type info to client;
end if;
/*
execute immediate with quotes
  'insert into sys_suppdata (property, value, key_name)
  location ''' || @supp_server || '.' || @supp_db || '''' ||
  ' {select property, value, key_name
     from sys_suppdata
   where  key_name    = ''Approve_Deny_Description''
   or key_name     = ''Referral_Description'' }';
*/
-- Create SE Currency Table for Processing SE Results & Conversion
/* to prevent it from executing */

When reading this file thru shell script using the code below:

cat proc.txt | while read str
do
..
done

I want to ignore all the commented lines, whether single or multiple, i.e. between /* and */ and read all the other lines. Please suggest

ldns_pkt_tsig_sign

ldns(3) 						     Library Functions Manual							   ldns(3)

NAME

       ldns_pkt_tsig_verify, ldns_pkt_tsig_sign-

SYNOPSIS

       #include <stdint.h>
       #include <stdbool.h>

       #include <ldns/ldns.h>

       bool ldns_pkt_tsig_verify(ldns_pkt *pkt, uint8_t *wire, size_t wire_size, const char *key_name, const char *key_data, ldns_rdf *mac);

       ldns_status  ldns_pkt_tsig_sign(ldns_pkt  *pkt,	const  char  *key_name,  const char *key_data, uint16_t fudge, const char *algorithm_name,
       ldns_rdf *query_mac);

DESCRIPTION

       ldns_pkt_tsig_verify() verifies the tsig rr for the given packet and key.  The wire must be given too because tsig does not sign normalized
	      packets.
	      pkt: the packet to verify
	      wire: needed to verify the mac
	      wire_size: size of wire
	      key_name: the name of the shared key
	      key_data: the key in base 64 format
	      mac: original mac
	      Returns true if tsig is correct, false if not, or if tsig is not set

       ldns_pkt_tsig_sign() creates a tsig rr for the given packet and key.
	      pkt: the packet to sign
	      key_name: the name of the shared key
	      key_data: the key in base 64 format
	      fudge: seconds of error permitted in time signed
	      algorithm_name: the name of the algorithm used
	      query_mac: is added to the digest if not NULL (so NULL is for signing queries, not NULL is for signing answers)
	      Returns status (OK if success)
