Jun 24, 2010I have the following which works but think there must be a easier one-liner way of doing this which involves not writing to a file but have failed to find something that works This is what I have:
Code:

FILESIZE=$`cat "filesize.txt" | cut -f1
rm filesize.txt
I then use the FILESIZE to compare to a number.

Apr 22, 2011I am curious if perhaps I am doing something wrong extracting pages from a pdf doc using pdftk and creating a new file. I am only extracting the odd pages from the file and outputting them to a new file that is now only 20 pages instead of the input's 40 pages, yet the new output file is still 1.4Mb in size, the same as the original.
It seems strange to extract only half the pages of a large document and end up with a result that is the same size. how to streamline the resulting pdf's using pdftk?
BTW this is the command I am using, in case perhaps I am missing an option to optimize file size or something:
Code:
pdftk A=ch15.pdf cat A1-40odd output odd.pdf
CentOS 5 Networking :: Allow The User Only See The Size Of The File, And Not The File + Symbolic Links?
Feb 23, 2009I'm researching about symbolic links been used with samba / CIFS:I'd like that the user that uses a MS-Windows OS could see my shared folder on CentOS 5 and the symbolic links that are inside this folder. Well, it works but, the user will see that the size of the file is bigger than the real file. Apparently, CIFS gets the size of the symbolic link (aproxim.32K) and add it to the size of the file.Example 1: 100KB file, used with shared folder, MS-Windows's user will see 100KBExample 2: 100KB file, used with symbolic link inside a shared folder, MS-Windows's user will see 132KB. (Sym link + size of file)Is there a way to allow the user only see the size of the file, and not the file + symbolic links ?

Jun 13, 2011I was just testing specifying limit on file size to a user and have added the following to /etc/security/limits.conf bob soft fsize 100 This basically should have said not to allow bob to create anyfile greater than 100Kb in size.
But the interesting thing is, if bob already has any file which is greater than 100Kb in size, it even doesn't allow to log him into the system both from console and SSH. Also nothing is logged in logs.. How do I configure it so that, bob can login to the system even though he has any file greater than 100Kb (but doesn't allow him to create file which are greater than 100Kb) ??

Programming :: Why The Stack Size Limit
May 1, 2011Why is it in Linux that there is a stack size set by default? And why is it so small? (My system is set to 8192 kbytes.) And why is there a default limit on the stack size when the max memory and virtual memory size are, by default, unlimited? (Aren't they both fed from the same place ultimately?)
Reason I ask: I want to use recursive functions in my programming a lot more. Problem is, if the language (or implementation) doesn't happen to support tail-call recursion, then I can be pretty well certain that the first huge problem that gets thrown at my function is going to kill my program because the stack size limit is going to be quickly reached. Obviously, I can change the stack size limit for my own computers, but it doesn't feel so great knowing that most of the people who copy and execute my code will have probably have overlooked this. Anyway, does anyone know: is this small default stack size limit just one of those historical artifacts, or is there some technical reason for it?

May 17, 2011The last time I got involved with printers and fonts, printers had tractors and ribbons and the only codes in use were ascii and ebcdic. So even if I could remember it would be out of date. I've written a C program that writes a text file. I want to print it. I run it through expand and send it to lp, but it comes out in an undesirable primitive font.
Once upon a time, one sent a string of commands to the printer telling it what font to use and what size, etc. I dont think this is done anymore, and if it is I dont remember how to do it. I assume programs embed in their output instructions in some common format which tell this stuff to the printer - in my case a HP1020. I've been looking on the search engines but I haven't found the magic words to find what I want. how to get my output formatted. If it involves some escape sequences in the file, maybe a pointer to a description of which does what?
Programming :: Resident Set Size Increasing Continuously
Jun 13, 2010I am working on a C++ application, using the latest Slax as distro and CodeBlocks 8.02 as IDE.
I have a problem that is really biting me hard... And i'm sorry if my questions will sound trivial: i'm still a C++ noob...
Basically,looking with KSysGuard i can notice a constant increment of the VmRss parameter,i.e. the resident set size of my program.
While stepping with the debugger i noticed that the VmRss parameter increases by 4 (KB?) when i push_back into some STL vectors (i have this problem in various parts of the code).
While i analyze the problem with KSysGuard i'm also looking at the /proc/statm file of my process. When KSysGuard shows a VmRss increment by 4, i can actually see an increment (by 1) in the 2nd parameter of that file (which is the resident set size) but not in the 1st parameter (which is the total program size).
What surprises me most is that the VmRss is reported in KB and i really am not pushing 4 KB inside the vector all at once...
So i ask:
1)Is this a memory leak?
2)Why the total program size doesn't increase?
3)To me, it looks like VmRss increases "cumulatively" only after several insertions in the various vectors.

Programming :: Array Size Base On User Input?
Oct 27, 2010If I have an array which its size is based on the user input, from some material, I need to use malloc function to allocate memory for that array what is known dynamic array. Don't forget to free it.hat's fine, however, I like to try things out even I know the program will crash.I have written some test program on my Mac using C language like this:int width = 0;//get user input, and assign the input value to width, for example, 3char * array_var[width];and width is an int, its value will be assigned by the user input. The point is, this program work as expected, for example, in command line, I input 3, then array_var length is 3, its size is 3 * sizeof(char *).
