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

gri_merge

GRI_MERGE(1)						      General Commands Manual						      GRI_MERGE(1)

NAME

       gri_merge - merge multiple Gri output files into a single PostScript file.

USAGE (style 1):
	      gri_merge [OPTIONS] CxR a.ps b.ps ... > merged_file.ps

       Merges  the  files  onto one page, in 'C' columns and 'R' rows.	The CxR files are given in the order of words on a page.  The page is pre-
       sumed to be 8.5x11in in size, as are all the input files, and the input files are sized to fit, and kept in natural scale.

USAGE (style 2):
	      gri_merge [OPTIONS] xcm ycm enlarge a.ps [b.ps ...] > merged_file.ps

       Where `enlarge' is a scale factor applied after offsetting `xcm' to the right and `ycm' upward.

   EXAMPLE (style 2):
	      The following

       gri_merge 2 12 .5 a.ps 

	      12 12 .5 b.ps 

	      2 2 .5 c.ps 

	      12 2 .5 d.ps > all.ps

       produces 4 panels from gri plots done using margins and sizes as specified in the following lines in a gri commandfile

	      set x margin 2

	      set x size 15

	      set y margin 2

	      set y size 15

       The OPTIONS, available if your 'perl' has 'getopts' library, are:

       -u graylevel -- set graylevel for underlay beneath panels, by default 0.75.

	      Values range from 0 (black) to 1 (white), although a value of precisely 1 means do NOT draw underlay.

       -b graylevel -- Set value for background under individual panels, again 0

	      for black to 1 for white, with 1 meaning no drawing.

       -h     -- Print this help message and quit.
