Web Page Table Extractor allows quick and easy extraction of tables from web pages without the hassle of copying, pasting and reformatting of the data. The information can be modified then exported to a new html document, a standardized csv file (comma separated values) or basic text. CSV files can be utilized in spreadsheets or as databases to other programs. Web Page Table Extractor improves the accuracy of information transfer and eliminates the hassle of manual data transfer. This is an absolute must have for anyone that gets tabular data from the internet.

Features:

• Automates transfer of web page table data into various forms
• Improves accuracy of data while reducing involvement time
• Translates all tables found in the web page in one pass, allows individual selection of each table found
• Provides user display of translated tables that allows for easy modification before exportation
• An absolute must have for anyone that gets tabular data from the Internet

Ever used the terminal? Or even command prompt on windows? Ever thought it's not enough power and flexibility? Well rbShell is for you, it uses your system commands as well as being able to run ruby commands as well. For Example:

rbShell $ echo Hello World!
=> Hello World!

[Felicia@Felix:/] $ Puts RUBY_PLATFORM
=> i386-linux

Notice the prompts are different? You can customize your prompt easy, just by editing your .rbShell_conf file in your home directory.

Windows: C:\Documents and settings\user
Linux: /home/user
Mac: ?

Just edit the line that starts with Prompt=.
By editing this line you will change the prompt rbShell uses. The line default for:

Windows: Prompt="rbShell $ "
Linux&Mac: Prompt="[".blue + "#{ENV['USER']}" + "@" + "#{Socket.gethostname}" + ":".blue + "#{Dir.getwd}" + "]".blue + " $ "

Also notice there are colours? The colours are used to show
