In the mean time I have written one script which will give me the users last login in the system ( All users )
In the above I want to execute the first line command highlighted below as root using sudo..
ssh unadm@$1 ' lsuser -a time_last_login ALL | sed 's/\ time_last_login=/:/g' > /userlogins
Can anyone explain how can i use sudo in this remote command

Hi,
I understand that the ls command with "-l" option generates the "last modified time" of specific directory.
However, some generated results displayed the "last modified time" with detail about the last modified year, for example:
-rwxrwxrwx+ 1 smith dev 10876 May 16 2005 part2

Hi,
When retrieving parameters of a file using ls command i need to print the year part . When i do ls -ltr the following output is displayed

Here the year part is not displayed only Jan 8 is displayed.
Can any one... (9 Replies)
Hi All,
i want the last login details along with year.
i tried below command but not giving me the year of last login.

What is the uptime command output when the server is running more than one year?
My doubt is whether it show in number of days format or number years and number of days format?
For example, Assume the server is running 400 days 3 hrs 3 min 3 secs. The output like 400 days 3:3 min or 1 year 5... (3 Replies)

hi all,
I use
date +%Y
which gives Current year.
Requirement: I want previous year to be printed. Please help me.
Note: I tried

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_Surface *surface;
Uint32 temp, pixel;
Uint8 red, green, blue, alpha;
