Fresh Ubuntu

There are over 130 Linux distributions (versions) and they can be administered (managed) by Linux Graphical User Interface (GUI) utilities - or by using Linux commands.

Linux GUI utilities give you a “point-and-click” interface for doing Linux administration tasks, like working with the Linux file system (to make directories and copy files), and to create Linux users. However, they are slow and awkward to use - and even worse, they are different from one Linux distribution to another!

On the flip side, Linux commands are virtually identical from one Linux distribution to another. So, when you learn a Linux command in one Linux distro, that same command will work in all 130+ Linux distros.

However, new Linux users often have difficulty learning how to use Linux commands to administer the Linux OS (operating system). This is because most Linux training materials are poorly written by Linux techies that don’t know how to write in plain English for people new to Linux.

Linux Tips: When you get Linux training, don’t spend time learning Linux GUI utilities - learn how to use Linux commands, even though they are a bit harder to learn than GUI utilities.

Linux Command Names

Linux command names are often an abbreviation of what the command does. For example, the rm command stands for remove.

Linux command names and command options are “case sensitive”. Lower case letters need to be typed in lower case and vice versa. You must type in a Linux command and the options of the command, exactly as shown.

Linux Tips: Be sure to put a space between the Linux command name, its options, and what the Linux command is being run “on”, such as the name of a file.

Linux Command Name Examples

Here are some Linux command examples. The task is described and then the Linux command name is shown.

make (create) a directory - the Linux command is md

create new Linux users - the useradd command is used for this

search the Linux file system for information - the Linux command is grep

see the “type” of a Linux file - the file command displays this information

see the names of new Linux users, currently working on the system - the Linux command is users

find Linux directories and files in the Linux file system - the command for this is called find

Linux video tutorials are an easy and fast way to get Linux training and actually “see” how to use Linux commands.

When you watch a Linux video tutorial, you get to see, hear and do! You see and hear how to run a Linux command and you can even pause the presentation so you can run the Linux command yourself!

I received an email recently that brought me back to reality and was the entire reason why I started the podcast. So, before I get entirely off track I thought I would devote the main segment of the podcast to going back to basics. I do this because the podcast can potentially get new listeners every six or so months, mostly due to the Ubuntu release cycles. And, I think that is good for the podcast, but, not so good for new listeners who just come on board. Now, I realize that it is just as easy to go back and get prior episodes but who has the time? So, with that in mind you can download

Here are the links to the news items mentioned in the podcast.

Ubuntu Chooses Not to Enable 3D Desktop By Default

Feisty Fawn Herd 5 Released

Ubuntu Live In My Backyard!!

For the package of the week, I chose gPodder. Yet another podcatcher, but this is really simple and elegant. It is also in current development, and licensed under GPL. Like I said in the podcast, “Liferea makes for a great feed reader and also handles podcasts nicely. But, gPodder is a great alternative for downloading all those podcasts that you listen to. the link is here.

Oh, and before I forget, here is a good tutorial for installing packages from source and a few nice ubuntu tips.

If you are looking for a good review of Feisty Fawn Herd 3 you can find it on Peter Nikolaidis’ blog.

Well, that about does it for links. I hope I didn’t miss any. Just let me know otherwise and I will provide them for you. Just one more link to add and that is form ZIM whose song I played at the end of the podcast call ‘Misnomer’. A deeply melodic and engaging tune that I hope you’ll all like. Here is the link to his page.

Hi everyone!!

Sorry for the short just too many things going on this past week. This week I introduce you to the Gizmo Project which is another Voip product similar to Skype. The reason why I like it is the free voicemail feature that they offer you. Also, it gives you and option to record your conversations easily for free!!! For a podcaster that is valuable. This was supposed to be the first installment of the linux equivalent segment, but I was just too excited to tell you about this to offer a real “equivalent”. Yes I know Skype is available for linux but I think gizmo is a good alternative to Skype. I am astounded by its feature set that they offer for free. I’ll try harder next time to get out a better windows equivalent package.

I also explore wildcards. You may be already familiar with the asterisk (*) which can represent any number of characters. Below is a list of wildcards and proper syntax. Enjoy!!

The asterisk (*) - used for any number of characters. It can be used like this:

ls *.txt

This will list all the text files in the current directory.

The question mark (?) - used to denote a single character. It can be used like this:

ls p12000??.png

This will list all png files (it’s a graphics file good for websites) that start with p12000 as shown before the question marks, but the question marks are a place holder for any character at the position where the wildcard is placed.

If you wanted to find a file which contains a letter or number form a specific subset you could use the square brackets, []. For example:

rm fresh[k,x]ubuntu.txt

This will, of course, remove any text file freshkubuntu or freshxubuntu. But why would you want to do that??

You can also use the brackets for contigiuous sets of letters or numeral, such as, a-b, or 1-9. This is shown below:

copy vacation[a-c]200[0-6].* /home/harlem

As you can see, wildcards can be mixed to give even greater flexability to your commands. Now don’t fall asleep on me, I just have a couple more to go!

You can also use the brackets to limit your search by eliminating letters that a file does not contain by introducing an exclamation point after the first bracket and before the first letter, like:

ls [!fresh].pdf

This command will only show files that do not contain the LETTERS f, r, e, s, h, and inadvertently the word fresh. You can do the same to a range of letters, such as, a-w.

What if you wanted to search for a file that has a specific word in it? Well, you would use curly brackets, {}. Its not apparently intuitive, what with all the square ones dominantly in use. For example:

mv {fresh,ubuntu,is,the,best,podcast,ever} /home/toptenondigg

This finds files with the words in the given subset and moves it to the appropraite directory.

Note - These wildcards can be used with a number of commands, not just the ones listed here. Remember, use caution when moving things around with wildcards. Just be safe and if you are at all unsure about what you are doing stop and think about it. That’s it for now, see you next week.

Welcome

I know, I know, it was a lame joke and I promise it will never happen again. Well, at least I hope so;) Anyhoo, this week I installed Flash 9 Beta on my laptop and it works very great and exceeds my expectations. If you have already tried the tutorial please be aware that using untrusted repositories are to be used AT YOUR OWN RISK!! I myself did not have any problem with it nor do I anticipate any. I would being doing a great disservice to my listeners if I did not include the following;

My advice is when using untrusted repositories (ie, not certified safe by Ubuntu developers) you do so at your own risk. If you feel that the repository that you just used to install the Flash 9 Beta is suspect please delete it from your sources.list using the same edit technique described in the podcast.

I must reiterate that Trevino’s repository is BELIEVED to be safe, but in any case, no offense to Trevino, adjust your repositories list according to your own level of trust. I will tell you at this point that the reason Ubuntu is secure is that they only recommend and use trusted repos meaning that they have been checked (for lack of a better word) for possible threats. So, please be wise with any new repositories that you might come into contact with and judicious in your use of them.

Here is the link to the website:

Flash 9 from everythingwlse.blogspot.com

• Item 1 - Legal Victory for Open source
• Item 2 - Alternatives to Windows Programs
• Item 3 - Ubuntu Feisty Fawn Release Dates

CLCOTW

Well this weeks CLCOTW is not exactly a command but it is a good tip!

Just remember if you forget the spelling of the command just press the TAB key and it will either finish the command for you or give you a list of commands that start with the letters that you typed.

Ubuntu disks Available

If you would like to have an Ubuntu Dapper Disk please contact Michael Castellon, here is his email and his website address:

Michael Castellon

michaelcastellon@gmail.com
www.michaelcastellon.com

He has about 50 of the factory disks complete with sleeve and is willing to part with them. Thank you Michael for providing this service for my listeners.

Well, See you all next week, Ciao!!

Hello and welcome back! I now have this podcast in Ogg Vorbis format the feed for that is located at http://feeds.feedburner.com/freshubuntuogg just copy the link and put it into your podcatcher

This week I did some this includes

ls - list command that returns a list of the contents in the directory
mkdir - This command will allow you to make a directory
cd - This command will allow the user to move to another directory
cp - Copy command, this will copy a file from one directory to another
rm - deletes a file
mv - renames or moves a file
locate - helps find a file

Also I have a list of further resources for you to either find help or more information:

http://gnomefiles.org/ this is a good site to find packages for manual download among other things, it also has links to other good things

http://sourceforge.net/ Much like gnomefiles.org, has lots of packages for download

http://www.linux.com/ This is a great place to find out about news regarding linux in general and to find great tutorials

I also get a lot of news about Ubuntu from digg.com

Note: I will generally do a google search specifically for help on certain things rekated to ubuntu by specifically entering “ubuntu” as one of the search criteria. This usually gets me very close!!

Lastly, I like to listen to linuxreality.com podcast with Chess Griffin

Best of luck to you and I’ll be speaking with you later.
