Hi Belajesuri,
Thanks alot for your Perl code and to the others also I would like to say thanks so much but I need a Perl script.
I try to reformat your code from one-liners to the common way of Perl language and it works.
My next question is how I can set the header "Linux" and "UNIX" as variables instead of static values?. so when the other line comes, the header will be added also as well as the value of CPU anf MEM (e.g. )?.
so the result will be = NAME TIME Linux UNIX WINDOWS.. so on

Hi Balajesuri,
I've made the script based on your original code and the desired output already oke. But I think my script is still ugly. may be you have a good solution for this?.
A file content have
1 1:-0.289433 2:0.833778 3:0.314471 4:-0.289433 5:-0.81876 6:-0.456693 7:-0.17511 8:-0.644555 9:-0.00666341 10:-1.13603
I will like to have that column into row with numbers to be printed (red color) only after colon
output shud be like that
-0.289433... (1 Reply)
hi,
I have a requirement where in I read the values from a file using awk. The resulting data should be converted into row format from column format.
For ex: My log file login.lst contains the following
SERVER1 DB1
SERVER2 DB2
SERVER3 DB3
SERVER4 DB4
I use awk to grep only the server... (6 Replies)
Getting tired of cut-and-paste...so I thought I would post a question.
how do I change this column output to a single row?
from this:
# vgdisplay -v /dev/vgeva05 | grep dsk | awk '{print $3}'
/dev/dsk/c6t0d5
/dev/dsk/c11t0d5
/dev/dsk/c15t0d5
/dev/dsk/c18t0d5

Hi all!
I have this kind of output:
a1|b1|c1|d1|e1
a2|b2|c2
a3|b3|c3|d3
I would like to transpose columns d and e (when they exist) in column c, and under the row where they come from.
Then copying the beginning of the row.
In order to obtain:
a1|b1|c1
a1|b1|d1
a1|b1|e1
a2|b2|c2... (1 Reply)

SDL_PixelFormat(3) SDL API Reference SDL_PixelFormat(3)NAME
SDL_PixelFormat - Stores surface format information
STRUCTURE DEFINITION
typedef struct SDL_PixelFormat {
SDL_Palette *palette;
Uint8 BitsPerPixel;
Uint8 BytesPerPixel;
Uint8 Rloss, Gloss, Bloss, Aloss;
Uint8 Rshift, Gshift, Bshift, Ashift;
Uint32 Rmask, Gmask, Bmask, Amask;
Uint32 colorkey;
Uint8 alpha;
} SDL_PixelFormat;
STRUCTURE DATA
palette Pointer to the palette, or NULL if the BitsPerPixel>8
BitsPerPixel The number of bits used to represent each pixel in a surface. Usually 8, 16, 24 or 32.
BytesPerPixel The number of bytes used to represent each pixel in a surface. Usually one to four.
[RGBA]mask Binary mask used to retrieve individual color values
[RGBA]loss Precision loss of each color component (2^[RGBA]loss)
[RGBA]shift Binary left shift of each color component in the pixel value
colorkey Pixel value of transparent pixels
alpha Overall surface alpha value
DESCRIPTION
A SDL_PixelFormat describes the format of the pixel data stored at the pixels field of a SDL_Surface. Every surface stores a SDL_PixelFor-
mat in the format field.
If you wish to do pixel level modifications on a surface, then understanding how SDL stores its color information is essential.
8-bit pixel formats are the easiest to understand. Since its an 8-bit format, we have 8 BitsPerPixel and 1 BytesPerPixel. Since BytesPer-
Pixel is 1, all pixels are represented by a Uint8 which contains an index into palette->colors. So, to determine the color of a pixel in a
8-bit surface: we read the color index from surface->pixels and we use that index to read the SDL_Color structure from surface->for-
mat->palette->colors. Like so:
SDL_Surface *surface;
SDL_PixelFormat *fmt;
SDL_Color *color;
Uint8 index;
.
.
/* Create surface */
.
.
fmt=surface->format;
/* Check the bitdepth of the surface */
if(fmt->BitsPerPixel!=8){
fprintf(stderr, "Not an 8-bit surface.
");
return(-1);
}
/* Lock the surface */
SDL_LockSurface(surface);
/* Get the topleft pixel */
index=*(Uint8 *)surface->pixels;
color=fmt->palette->colors[index];
/* Unlock the surface */
SDL_UnlockSurface(surface);
printf("Pixel Color-> Red: %d, Green: %d, Blue: %d. Index: %d
",
color->r, color->g, color->b, index);
.
.
Pixel formats above 8-bit are an entirely different experience. They are considered to be "TrueColor" formats and the color information is
stored in the pixels themselves, not in a palette. The mask, shift and loss fields tell us how the color information is encoded. The mask
fields allow us to isolate each color component, the shift fields tell us the number of bits to the right of each component in the pixel
value and the loss fields tell us the number of bits lost from each component when packing 8-bit color component in a pixel.
/* Extracting color components from a 32-bit color value */
SDL_PixelFormat *fmt;
SDL_Surface *surface;
Uint32 temp, pixel;
Uint8 red, green, blue, alpha;

fmt=surface->format;
SDL_LockSurface(surface);
pixel=*((Uint32*)surface->pixels);
SDL_UnlockSurface(surface);
/* Get Red component */
temp=pixel&fmt->Rmask; /* Isolate red component */
temp=temp>>fmt->Rshift;/* Shift it down to 8-bit */
temp=temp<<fmt->Rloss; /* Expand to a full 8-bit number */
red=(Uint8)temp;
/* Get Green component */
temp=pixel&fmt->Gmask; /* Isolate green component */
