Last access time for file

2010-02-03 1 min read C Programs Linux

The C program will print the last access time for the file.

This is quite helpfull program when you want to find old files. Modifying the source to take the filename as argument and take multiple arguments is left as an exercise.

#include <stdio.h>
#include <sys/stat.h>
#include <sys/types.h>
#include <fcntl.h>
#include <time.h>
#include <stdlib.h>
int main(void)
{
    char datestring[80];
    struct stat a;
    //int fd = open("ak",O_RDONLY);
    if (stat ("iptc.c", &a) == -1) {
        perror("stat");
        printf (" Error");
        return;
    }
    printf (" Last Access Time is %s", ctime(&a.st_atime));
    printf (" Last Access Time is %s", a.st_atime);
}

Built-in lists in vim

<a class="zem_slink freebase/en/vimscript" title="Vimscript" rel="wikipedia" href="http://en.wikipedia.org/wiki/Vimscript">Vimscript provides excellent support for operating on collections of <a class="zem_slink freebase/en/data" title="Data" rel="wikipedia" href="http://en.wikipedia.org/wiki/Data">data, a cornerstone of programming. In this third article in the series, learn how to use Vimscript’s built-in lists to ease everyday operations such as reformatting lists, filtering sequences of filenames, and sorting sets of line numbers. You’ll also walk through examples that demonstrate the power of lists to extend and enhance two common uses of <a class="zem_slink freebase/en/vim" title="Vim (text editor)" rel="homepage" href="http://www.vim.org/">Vim: creating a <a class="zem_slink freebase/en/user_defined_function" title="User-defined function" rel="wikipedia" href="http://en.wikipedia.org/wiki/User-defined_function">user-defined function to align assignment operators, and improving the built-in text completions mechanism.

statifier — Dynamic to Static

2010-01-24 2 min read Linux

<a href="http://statifier.sourceforge.net/">Homepage of statifier.

<span style="font-size: xx-small;"><span style="font-size: xx-small;">Statifier create from dynamically linked executables and all it’s libraries one file.
This file can be copied and run on another machine without need to drag all it’s libraries.

<span style="font-size: xx-small;"><span style="font-size: xx-small;">Dynamically linked executables are smaller then statically linked.
From the other side dynamically linked executables use shared libraries compiled in PIC (position independend code) which is slower than ”normal” one.

Short Information about loaded kernel modules

2010-01-24 2 min read Linux

There are couple of ways you can find the information on the <a class="zem_slink" title="Loadable kernel module" rel="wikipedia" href="http://en.wikipedia.org/wiki/Loadable_kernel_module">loadable kernel modules. All these would always involve calling <a class="zem_slink" title="Lsmod" rel="wikipedia" href="http://en.wikipedia.org/wiki/Lsmod">lsmod to get the loaded kernel modules and then calling modinfo to get the info on the loaded modules. I will show you with examples:

$ lsmod
Module                  Size Used by
cdc_acm                19616 0
vfat                    8744 9
fat                    41836 1 vfat
