Not sure I like the sight of wild cards in something like that ..
what if the folder:
Task_old_Logs1
gets created?
I tested on my system (Solaris) - and this works - any reason why you just don't wrap the whole thing in double quotes ?? [edit] or is that not something cron likes ?? [\edit]
Hi,
I need to know how I'll be able to write a script that can goto a different dir where I don't have access to read,write and execute and also to run a commandline prompt in that dir with one file whose path has to be specified in that command.
Will I be able to do this?
Any ideas or... (2 Replies)
hi all,
i'm looking for a bash or tcsh script that will clone an empty dir tree 'over' another tree ...
specifically, i'd like to:
(1) specify a src directory
(2) list the directory tree/hiearchy beneath that src dir, w/o files -- just the dirs
(3) clone that same, empty dir hierarchy to... (2 Replies)
OK I am trying to use something similar to this:

echo "OK, starting now..."

cd pub

put filename.txt

only difference is the dir I need to cd to has a space in it like this

Hello!!
I have directories from 2008, with files in them. I want to create a script that will find the directoried from 2008 (example directory:

Of course, right at the end of the day I see that my "/" file system is just about out of space. I've been googling and reading man pages, but my google-fu is weak today.

Hello all,
I'm very new to shell scripting and need quite urgently to do this thing for my student job. I have a directory called "vectors" with a bunch of files all named ".vector". also i have for each of those files a directory with the name . I now want to move each of those *.vector files... (2 Replies)
We have a script which when run consumes the space of the disk from where it is being run. we have to kill this script every time to release space.
why do this happen ? any work around please
we are using solaris 10
P.S. : a part of the code will make some connection to the DB (1 Reply)
I have a script that I am trying to use. I need it to run from a certain directory. I have tried the following:

I have tried to run it. but I always get "no such file or directory" from the script... (5 Replies)

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;
