This is how to extract a .tar.gz file using Gunzip:
gunzip -c /path/to/folder/filename.tar.gz
To view a list of files in an archive use:
gunzip -c /path/to/folder/filename.tar.gz | tar -tvf -
To extract a single file use:
gunzip -c /path/to/folder/filename.tar.gz | tar -xvf – path/within archive/filename.php
There are many times when you may need to get the contents of another file on a server with php. Rather it is XML, html, or an RSS feed this is how to do it. The best way of doing this is to use this:
function fetch_content($url) {
$crl = curl_init();
$timeout = 5;
curl_setopt ($crl, CURLOPT_URL, $url);
curl_setopt ($crl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($crl, CURLOPT_CONNECTTIMEOUT, $timeout);
$ret = curl_exec($crl);
curl_close($crl);
return $ret;
}
You should now have the content of the $url stored in a string calue. Note that this will not fetch any supporting files such as CSS of javascript. You will have to further parse these files to store their contents into a seperate string value.

The file browser in Ubuntu provides the ability to run scripts on a selected file. These scripts can be used to do anything from opening a file to zipping or uploading, or anything that you can do from the command line.
To start this off open up a terminal window and type in:
gedit ~/.gnome2/nautilus-scripts/Open\ with\ gedit
Just copy and paste in this script found on the G Scripts site.
#!/bin/bash
#
# Nautilus script -> open gedit

filesall=””
while [ $# -gt 0 ]
do
files=`echo “$1″ | sed ’s/ /\?/g’`
filesall=”$files $filesall”
shift
done
gedit $filesall&
Save and close that Gedit window and execute this command to make the file executeable:
chmod u+x ~/.gnome2/nautilus-scripts/Open\ with\ gedit
This should be the result when you right click a file:
If you are looking for a way to quickly and easily block an IP from connecting to your server using the IPtables firewall then just use this script.
First off you need to make yourself root. Then you type in:
vi /usr/local/bin/blockip
Then just paste in this code:
#!/bin/sh
if [ "$1" != "" ]; then
/sbin/iptables -I INPUT -s $1 -j DROP
else
echo “Type an IP”
echo “Usage:”
echo ” Blockip <ipaddress>”
echo “”
fi
After you get that done you need to make the file executable, so just run this command:
chmod u+x /usr/local/bin/blockip
Now all you need to do to block an ip is type in the command like this (remember to change the IP to the one that you want to block) :
blcokip 20.2.2.20
That’s all there is to it! If you encounter any problems with this script please let me know, but I tested it and it should work.
The chances are that you are reading this because you are wondering what in the world svchost.exe is and why it is running on your system.
What Is It?
Microsoft’s explanation for what svchost.exe is is:
svchost.exe is a generic host process name for services that run from dynamic-link libraries
So what does this mean in human speak you may ask? Awhile back Microsoft decided to start moving its internal Windows services into .dll files instead of .exe files. This is how svchost.exe came to be. This is why if you ever take a look at your running processes you will notice that there are many svchost.exe instances running. This is because if all of the processes ran under just one instance all of Windows could be brought down by one failure. This is why they are spread out amongst many different processes.
What can I do about this?
You may ask how you can trim this list of svchost.exe processes down to size. well, for starters you can disable process that you don’t absolutely need running. Also if one of the process seems to be taking an extensive amount of CPU cycles you can always try restarting the process. The hardest part is finding out what process is controlled by what svchost.exe instance. To check go to command prompt and type:
tasklist /SVC
The only problem with using this method is that some of these names can be a little bit cryptic and hard to figure out. Another option is to right click on the process in the task manager and choose the “Go to service(s)” Option. This will cause all of the processes running under that svchost.exe to be highlighted.
Disabling Services
Go to the administrative tools tab in the control panel and open up services or simply type services.msc into run.
Find the process that you want to disable and just double click it.
I hope that this can be of help to somebody!
