A hidden functionality in Windows allows you to right click on a file, select Copy To Folder or Move To Folder, and the move to box will pop up and let you choose a location to either copy or move the file or folder to.
Like anything else on linux, it’s easiest to do things from the command line. Open up a terminal window and type in the following commands
You will often have the need to access data that resides on another server, whether you are writing an online RSS aggregator or doing screen scraping for a searching mechanism. PHP makes pulling this data into a string variable an extremely simple process.
Apache gives you a list of files in an empty directory by default, but sometimes you will want to show a list of files that are in a directory through PHP so that you can customize the output of the list, and make a “pretty” listing of files. Here’s the basic code to make a list.
Note: I’ve written an updated article for both Vista and XP
There are a number of ways to kill a process if you know the name of the process. Here’s a couple different ways you can accomplish this. We are going to assume that the process we are trying to kill is named irssi
A useful technique for your applications is allowing them to parse command line arguments. This can give a lot of extra functionality to your application, for instance to pass the name of a file to open on the command line.
When you are programming a Windows Forms application, you will invariably need to get variables from a second form window, such as an options form or popup search prompt.
If you have an unwieldy text file that you are trying to process, splitting it in sections can sometimes help processing time, especially if we were going to import a file into a spreadsheet. Or you might want to just retrieve a particular set of lines from a file.
Setting up an SSH server on Ubuntu is about as simple as it gets. The server of choice is OpenSSH.
The ASP.NET development environment on Ubuntu Linux is called XSP. This is a simple webserver written in C# that can be used for either ASP.NET 1.0 or 2.0 applications. You can install both environments side by side if need be.
When you are trying to install software on Ubuntu or Debian linux using the apt-get package system, quite often you’ll forget the exact name of the package you are trying to install. Here’s how you can get a little help figuring out what the name is.
There is no easier way to get your Ubuntu installation up and running with the tools you need than Automatix. I’m not entirely certain why this hasn’t been integrated into the core of the system yet, because it’s about as easy as it gets.
If you are familiar with linux/unix, you will be very accustomed to the ability to kill (and start) processes from the command line. Linux gives you a very rich set of command line tools that simply don’t exist on Windows by default.
To interact with the services panel from the command line, Windows provides the Net utility. From the command prompt, you can use this utility to start, stop, pause and continue services. What most people don’t realize is that you can also use this to display a list of services that are running on your computer.
For this exercise, we will use the mysqldump utility the same as if we were backing up the entire database.
From a command prompt or terminal window, run this command:
Very simple, either use the clear command:
Run this command from a terminal window. This works on debian, ubuntu, and redhat. I’m sure it works on others but those are the only ones I have access to.
This approach works for any linux operating system, including Ubuntu, and is probably most often used in conjunction with web development work.
If you are doing any kind of PHP development, you’ll almost always be using Apache along with it. Here’s the quick and easy way to get PHP up and running on your Ubuntu box.
Repositories on Ubuntu are the locations that you can download software from. As a general rule, the default repositories don’t contain the right locations for most software packages that you’ll want to install. You will want to open up the /etc/apt/sources.list file, find and uncomment the following lines
There are many reasons you would want to restore a database from a backup file… But you should also test this on a test server just to make sure that your database backups are working correctly. Here’s the syntax:
Backing up your database is a very important system administration task, and should generally be run from a cron job at scheduled intervals. We will use the mysqldump utility included with mysql to dump the contents of the database to a text file that can be easily re-imported.
For every database, you should set the root or sa passwords to something other than the default, unless you want to get hacked. For mysql, the system administrator user is called root. You will use the mysqladmin utility from a command line to set the new password. Notice that there are two commands to be run.
