Startup animation and theme for Fedora 12 onwards.

Thu, 20 May 2010 16:43:31 +0000

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.

Finding all the executables/binary in Linux rpm based distro.

Sun, 03 Jan 2010 22:40:14 +0000

I have been thinking about this for quite sometime now, how to find all the executables on the linux system. One of the way is to do a ”ls” on all the directories in the PATH variable. But that will not list the executables that are outside of the PATH. So, I wrote this one liner :

rpm -qal |agrep ”bin\/” > all_execs

This will list all the files in the Linux system in bin or sbin directory and that should be pretty much all the binaries in the system.
