Thanks Don- Will check the performance and update you.

I am also looking to write in one line code something like below..

Code:
cat test2.tlog | awk 'BEGIN { record_type=${record%"${record#????}"}; 
if (record_type == 1111) {a1=100; a2=0; a3=0; a4=0; a5=0; a6=0; a7=0;a8=0; a9=0} 
if (record_type == 2222) {a2=$(( a2 + 1 )); a3=$(( a3 + 2))} 
...
...
else printf $line_no$a1....$9;
printf $line_no$a1....$9
}' >> test1_all_data.log


Kindly let me know if you have any suggestions on this.

Thanks a lot Don for your support...

My initial script took around 21 min 35 sec, with the new code it is taking 15 sec.

NAME
SDL_CDOpen - Opens a CD-ROM drive for access. SYNOPSIS
#include "SDL.h" SDL_CD *SDL_CDOpen(int drive); DESCRIPTION
Opens a CD-ROM drive for access. It returns a SDL_CD structure on success, or NULL if the drive was invalid or busy. This newly opened CD- ROM becomes the default CD used when other CD functions are passed a NULL CD-ROM handle. Drives are numbered starting with 0. Drive 0 is the system default CD-ROM. EXAMPLES
SDL_CD *cdrom; int cur_track; int min, sec, frame; SDL_Init(SDL_INIT_CDROM); atexit(SDL_Quit); /* Check for CD drives */ if(!SDL_CDNumDrives()){ /* None found */ fprintf(stderr, "No CDROM devices available "); exit(-1); } /* Open the default drive */ cdrom=SDL_CDOpen(0); /* Did if open? Check if cdrom is NULL */ if(!cdrom){ fprintf(stderr, "Couldn't open drive: %s ", SDL_GetError()); exit(-1); } /* Print Volume info */ printf("Name: %s ", SDL_CDName(0)); printf("Tracks: %d ", cdrom->numtracks); for(cur_track=0;cur_track < cdrom->numtracks; cur_track++){ FRAMES_TO_MSF(cdrom->track[cur_track].length, &min, &sec, &frame); printf(" Track %d: Length %d:%d ", cur_track, min, sec); } SDL_CDClose(cdrom); SEE ALSO
