LPI Certification help and tutorials

For the last couple of days I have been very busy but not too away from my desktop. Though I did not get time to publish anything. Here’s one of my other favourite distributions. Its known as elpicx. This distribution is oriented towards LPI certification exams and contains some documents and links that are quite helpful.

Good thing is now it supports F9 with KDE.

I found that the documents in the distro are GPL and thus I dont think that there should be any issue in re-distributing the pdfs and the links, so <a href="http://amit.with-linux.com/elpicx/" target="_blank">here it is. If you find anything in these docs or links that I should not link or upload them, let me know. I wil remove them.

Startup animation and theme for Fedora 12 onwards.

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.

Display the history and optionally grep

Ever wondered how good it would be to have a command/function that would display the history or display the history with <a class="zem_slink" title="Grep" rel="wikipedia" href="http://en.wikipedia.org/wiki/Grep">grep.

Would be really good right, well someone thought about this 🙂

$ h() { if [ -z &#8221;$1&#8221; ]; then history; else history | grep &#8221;$@&#8221;; fi; }

Place this in your .bash_profile and you can use it two different ways. If you issue &#8217;h&#8217; on its own, then it acts like the history command. If you issue:

Working with FTP Directories.

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.

Solaris Tips and Tricks

A nice trick to list the process which has opened a particular port is :

#!/bin/ksh

# 7-30-2003
# find from a port the pid that started the port

line=&#8217;————————————————————————-&#8217;
pids=`/usr/bin/ps -ef | sed 1d | awk '{print $2}&#8217;`

# Prompt users or use 1st cmdline argument
if [ $# -eq 0 ]; then
         read ans?&#8221;Enter port you like to know pid for:  &#8221;
else
         ans=$1
fi

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

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&#8217;s a small script that I wrote to quickly check out all the icon themes that I have in my ~/.icons folder.

#!/bin/bash
[[ &#8221;$1&#8221; == &#8221;&#8221; ]] && time=5 || time=$1
[[ &#8221;$2&#8221; == &#8221;&#8221; ]] && (
cd ~/.icons
cont=&#8221;y&#8221;
echo &#8221;Select one of the icon themes&#8221;
echo &#8221;When you like some theme just press Ctrl+c&#8221;
for i in *
do
[[ -d $i/cursors ]] || (
echo &#8221;Now trying …. : $i&#8221;
gconftool-2 –type string -s  /desktop/gnome/interface/icon_theme &#8221;$i&#8221;
sleep $time
)
done
) || gconftool-2 –type string -s  /desktop/gnome/interface/icon_theme &#8221;$2&#8221;
