Hello sam_bd,

Could you please go through the following explanation and let me know if this helps you.

Code:

awk -F"="  '                           ###Set field seprator as "=" here.
  /SName/{               ###Looking for string SName in any line, if that is present i any line then perform following.
   VAL=$0;        ###create variable VAL and assign its value to current line.
   next           ###next is awk built-in keyword which will SKIP all next statements now.
                       }
        /ESys/  {               ###Searching for string "ESys" here in any line, if that is present then perform following.
   print VAL,$0   ###Print the value of variable VAL and current line too.
         }
           '  Input_file               ###Mentioning the Input_file here, which is getting processes by awk.

Thanks,
R. Singh

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
