rm -rf -file

Except that doesn’t work. My CentOS complained to me with the following message (though not all operating systems may supply this, so this is mainly for those whose OS does not supply this tip):

rm: invalid option -- 'l'
Try `rm ./-file' to remove the file `-file'.
Try `rm --help' for more information.

The suggested tip here works well. Simply running the following command should delete the “-file” file.

rm -rf ./-file

Keep in mind this limitation does not apply only to the rm command, but a large number of commands including touch and others. It is the most annoying for the rm command, since you are trying to remove the file. For these other commands, you would also have to prepend the file name with a ./ in order for this to work.

Take a look at the two images below of what my screen normally looks like, and what my screen looks like when the colors are inverted

Do keep in mind if you take any screenshots in the ‘inverted color’ mode, the screenshot will not come out with inverted colors. If you would like to have inverted colored screenshots, you must manually invert the image in an image editing program.

yum install gcc make libXext-devel libSM-devel libICE-devel zlib-devel libXfixes-devel libXdamage-devel libvorbis-devel libtheora-devel

Because CentOS does not official an RPM for recordmydesktop, we will have to install it from source. We will download a tar of the source code, untar the source, and remove the tar file:

wget http://downloads.sourceforge.net/project/recordmydesktop/recordmydesktop/0.3.8.1/recordmydesktop-0.3.8.1.tar.gz
tar xf recordmydesktop-0.3.8.1.tar.gz
rm -rf recordmydesktop-0.3.8.1.tar.gz

Now, let’s go into the folder and install Recordmydesktop.

cd recordmydesktop-0.3.8.1
./configure
make
make install

If you did not set a custom prefix, running /usr/bin/recordmydesktop should begin recording your desktop! Use the following command (just as with most commands) to view the options available:

recordmydesktop --help

To begin with, make sure you have the older version of Firefox/Thunderbird installed. This is necessary, as we are going to use their launch scripts as a template to create the launch scripts for the newer version.

To shorten things up, I will refer to Thunderbird as TB, and Firefox as FF. For the most part, I will refer to TB instead of both TB and FF. All you have to do is change where I write ‘thunderbird’ to ‘firefox’ and it will most likely work. To begin with, you want to download the latest version of Thunderbird or Firefox.

• 32 bit TB:

  wget 'http://releases.mozilla.org/pub/mozilla.org/thunderbird/releases/10.0-real/linux-i686/en-US/thunderbird-10.0.tar.bz2'

• 64 bit TB:

  wget 'http://releases.mozilla.org/pub/mozilla.org/thunderbird/releases/10.0-real/linux-x86_64/en-US/thunderbird-10.0.tar.bz2'

• 32 bit FF:

  wget 'http://releases.mozilla.org/pub/mozilla.org/firefox/releases/10.0/linux-i686/en-US/firefox-10.0.tar.bz2'

• 64 bit FF:

  wget 'http://releases.mozilla.org/pub/mozilla.org/firefox/releases/10.0/linux-i686/en-US/firefox-10.0.tar.bz2'

Untar and unzip the file you just downloaded (as said before, name may vary with the product you are installing). Afterwards, delete the tar file, which is no longer necessary.

tar xf thunderbird-10.0.tar.bz2
rm -rf thunderbird-10.0.tar.bz2

The simplest way is to delete the current TB/FF install, and move the newly downloaded files to the old directory. This command will vary for 32 and 64 bit systems. IMPORTANT: For Firefox, change the number 3.1 to 3.6 for both architectures. As for the commands, for 32 bit:

rm -rf /usr/lib/thunderbird-3.1/*
mv thunderbird/* /usr/lib/thunderbird-3.1/

For 64 bit systems:

rm -rf /usr/lib64/thunderbird-3.1/*
mv thunderbird/* /usr/lib64/thunderbird-3.1/

Congratulations! You are more or less done. Now, you may want to get rid of the empty FF/TB folder by running the command:

rm -rf thunderbird

That’s pretty much all. Running command ‘thunderbird’ or going to ‘Applications -> Internet -> Thunderbird Email’ will launch the newly installed version!

Beyond TB/FF 10, the ‘automatic upgrade’ feature should kick in. As you can see in the two screenshots above, TB and FF will automatically look for new versions, and will automatically upgrade when they exist. This way, you can run much newer versions than those found in the CentOS/RHEL repo.

Go under the Advanced tab, and under the Network tab. From there, click on Settings.

Choose Manual proxy configuration. Leave everything empty except the SOCKS Host and Port. The SOCKS host and port should be the respective host and port.

<form action="" method="post" enctype="multipart/form-data">
	<input name="uploads[]" type="file" multiple="multiple">
	<input type="submit" value="Upload!">
</form>

Note the name of the <input> is uploads[], with a bracket. While the bracket is not required for multiple file selection, it is required for PHP to process the files. The following PHP snippet can be used to process the files uploaded using the code above:

<?php
if($_SERVER['REQUEST_METHOD'] == 'POST') {
	foreach($_FILES['uploads']['name'] as $id => $name) {
		rename($_FILES['uploads']['tmp_name'][$id], 'uploads/' . $name);
		echo "<p>$name uploaded successfully!</p>";
	}
}
?>

The PHP script will take all the files uploaded and place them into a folder named ‘uploads’. For it to work, the uploads folder will need to exist already, and needs to be writable by the web server. It’s recommended that you DO NOT use the exact PHP script in a production environment, as it’s dangerous to not check the file being uploaded. You don’t want others uploading a malicious PHP file and executing it on your server.

Click on Network and Sharing Center.

On the left side under ‘Tasks‘, click ‘Manage Network Connections‘.

Right click on ‘Local Area Connection‘ and click ‘Status‘. From there, click on ‘Details‘.

You will be presented with a whole list of information. Note down the ‘IPv4 Subnet Mask‘, ‘IPv4 Default Gateway‘, and the two ‘IPv4 DNS Servers‘. Afterwards, simply clock Close.

Right click on ‘Local Area Connection‘ again and click ‘Properties‘. Highlight ‘Internet Protocol Version 4 (TCP/IPv4)‘ and click on Properties.

Choose ‘Use the following IP address‘ and fill in the fields with the information provided previously when you clicked Details. This will be the settings for your first IP address.

To specify the additional IP addresses, click on Advanced. Click ‘Add‘ under ‘IP addresses‘ to add more IP addresses.

The ‘IP address‘ should be the IP address. The ‘Subnet mask‘ should be same as the one for the first IP address.

From there, click Add, OK, OK (and so on) to save and apply these settings.

You will be presented with the Add Roles Wizard. This wizard will guide you through the installation of IIS 7.

When on the Server Roles page, you will be able to select which roles you wish to install. In our situation, we want to install Web Server (IIS).

In order to setup the IIS web server, you will have to install a few additional features as well. You just have to click Add Required Features to install those as well.

After choosing to install IIS, you will be presented with an introduction to the web server, which will tell you a bit about the server itself. You don’t have to read it, but you may find the information helpful to know.

After reading the IIS introduction, you will have an opportunity to custom your IIS install. You can include services such as ASP.NET, ASP, CGI, SSI, among many others.

Before the actual IIS installation takes place, you will be presented with a summary of what will be installed. After reviewing the information, click Install to finally install the server.

The server installation process can take a while. The speed really depends on the server you are installing it on. It isn’t a bad time to take a coffee break or something of that sort.

After the installation has completed, you will be presented with the Installation Results page. Hopefully it tells you everything has been installed successfully.

After starting the IIS server, you will be able to test it on http://localhost/!

client_max_body_size 4M;

The number 4 should be changed to however megabytes you want the limit to be. Do note it’s 4M for 4 megabytes, rather than 4MB. After having added that to your configuration file, you should restart nginx for this change to take effect. Do note the command may differ, but should be the following if you installed from a RPM/DEB package or setup the startup script from our Nginx Startup Script post.

/etc/init.d/nginx restart

Even after increasing nginx’s upload limit, the PHP limit may also be limiting how large of a file you can upload. You will want to change the post_max_size and upload_max_filesize values in your php.ini file as well. Note that if you make a change here, most likely you will have to restart the spawn-fcgi process to make the change live.
