Web Thumbnails, create your account to upload your files.

2010-02-04 1 min read Linux

So, since I got one more address, I thought of some social service too ;). Just kidding. Got my gallery site up. You can use it too to upload your photos. For stopping social abuse I would personally be montoring the accounts thus created and you would need to send a mail to gallery@amit-agarwal.co.in for creation of the account. Right now there is no quota on the size of the space.

Color output from ls – based on file type

2010-02-04 1 min read Bash Linux

Threre are certain default variables which control the color of the output from the ls command, so we will talk about them today.

The first one is to get the color output from the ”ls” command. We will look at the various ways to do this:

First is to use this with default colors:

ls –color=auto

Now this will use the default colors which might not go with your liking 🙂 So if you want to change the colors you can use the variable called LS_COLORS.

Setting the title of PuTTY window.

2010-02-04 1 min read GNOME Linux

Setting the title for PuTTY window is quite a simple trick. The trick is to set the PS1 with a escape sequence. When the PS1 is set with the escape sequence the variable will set the title window also. And not only can this trick be used in PuTTY but even on gnome-terminal to set the title dynamically. You can use this in the .bashrc or .bash_profile file to do it whenever you are starting the terminal.

Gentoo, Knoppix and Linux Console Screenshots

2010-02-03 2 min read Linux

Finally I decided to try a few distro’s that I downloaded with Beldi.

Gentoo: Quite Small distribution. Did not configure my DHCP address and also did not start a X window also so did not try too much.

Knoppix: Well known for its recovery functions, the Live CD does discover all the hardware and boots pretty nicely to the X windows directly with the ethernet configured.
I specially liked the fact that the boot up to X window theme looked quite similar and the background did not change which is quite soothing. And no doubt the desktop background included by default is quite good.

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);
}

<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.
