Startup animation and theme for Fedora 12 onwards.

2010-05-20 1 min read Fedora Learning Linux

Since the release of <a class="zem_slink freebase/en/fedora" title="Fedora" rel="homepage" href="http://fedoraproject.org/">Fedora 12, fedora is using plymouth. Plymouth kicks in just after grub and before the Xserver starts.

Description:

Plymouth provides an attractive graphical <a class="zem_slink freebase/en/bootsplash" title="Bootsplash" rel="wikipedia" href="http://en.wikipedia.org/wiki/Bootsplash">boot animation in
place of the <a class="zem_slink freebase/en/text_messaging" title="Text messaging" rel="wikipedia" href="http://en.wikipedia.org/wiki/Text_messaging">text messages that normally get shown. Text
messages are instead redirected to a <a class="zem_slink freebase/en/data_logger" title="Data logger" rel="wikipedia" href="http://en.wikipedia.org/wiki/Data_logger">log file for viewing
after boot.

Working with FTP Directories.

2010-05-19 1 min read Linux

If you have to manage some ftp site, I can understand you pain in managing the site with FTP. Specially if you are managing a site where you need to edit the files. Without shelling out some decent amount of money you will not get decent editor which can help you edit the files directly over ftp. So today I spent my time looking for a good solution and UREKA I found it.

bash script to change icon theme to check out all the installed themes (personal)

2010-05-19 2 min read Fedora GNOME Linux

I am really annoyed with the time that is required and the number of clicks that it takes to change the gnome icon theme. So here’s a small script that I wrote to quickly check out all the icon themes that I have in my ~/.icons folder.

#!/bin/bash
[[ ”$1” == ”” ]] && time=5 || time=$1
[[ ”$2” == ”” ]] && (
cd ~/.icons
cont=”y”
echo ”Select one of the icon themes”
echo ”When you like some theme just press Ctrl+c”
for i in *
do
[[ -d $i/cursors ]] || (
echo ”Now trying …. : $i”
gconftool-2 –type string -s /desktop/gnome/interface/icon_theme ”$i”
sleep $time
)
done
) || gconftool-2 –type string -s /desktop/gnome/interface/icon_theme ”$2”

Disk identification by UUID in Fedora.

2010-05-19 2 min read GNOME Linux

Yesterday I managed to delete my complete /usr directory and thus had to re-install my OS but I learned something new yesterday which I didn’t know earlier or actually never bothered to find out.br /br /All the partitions are mounted by udev using the UUID or label now. Finding the label of setting the label is easy but that was not the case with UUID (at least till you dont know how to do it). So finally I set my foot to search it. Heres some of the things that I found:br /br /bblkid/b – Gives you a list like below for all your partitions:br //dev/sda6: UUID=”8D8A-6CF1” TYPE=”vfat” LABEL=”Backup” br /So this is sufficient to modify your fstab to refer to the UUID or label instead of the drive. So whats the change in fstab. If the earlier entry looks likebr //dev/sdb6nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp; /media/Bkup3nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp; vfatnbsp;nbsp;nbsp; uid=500,nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp; 0 0br /then you can change this to :br /UUID=”8D8A-6CF1”nbsp;nbsp; /media/Bkup3nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp; vfatnbsp;nbsp;nbsp; uid=500,nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp; 0 0br /What is the benifit:br /———————br /When you re-format your Hard Disk there is a likely possibility that the dev name could well change and thus completely changing the mount points for all your fstab entries. This is really a pain if you have 10 or more partitions like the way I have. So if you use label or UUID then they never change and your mount points remain the same.br /br /Effective use: Use autofs package to automatically mount all your partitions. Autofs mounts the package at /media/LABEL, so before you hit to start your autofs label all your disks.br /br /Other ways to find the disk labels and UUID’s:br /ls /dev/disk/by-uuid –gt; simplest way. :)br /br /Will get back to this later with more details.br /br /

Mirror or download a website with a tool much better than wget

2010-05-19 1 min read Bash Fedora Linux

If you want to mirror a <a class="zem_slink freebase/en/website" title="Website" rel="wikipedia" href="http://en.wikipedia.org/wiki/Website">website, the simplest tool I know if is <a class="zem_slink freebase/en/wget" title="Wget" rel="homepage" href="http://www.gnu.org/software/wget/">wget. Once you have used wget, you know the troubles associated with it. You also get added couple of files as search html files, which are useless and wastage of bandwidth for you as well as the <a class="zem_slink freebase/en/web_server" title="Web server" rel="wikipedia" href="http://en.wikipedia.org/wiki/Web_server">webserver.
