Creating a New File with Ruby
New files are created in Ruby using the ''new'' method of the ''File'' class. The ''new'' method accepts two arguments, the first being the name of the file to be created and the second being the mode in which the file is to opened. Supported file modes are shown the following table:
 
<table border="1" cellspacing="0" width="100%">
<tr style="background:#efefef;">
<th>Mode<th>Description</th>
<tr>
<td>r<td>Read only access. Pointer is positioned at start of file.</td>
<tr>
<td>r+<td>Read and write access. Pointer is positioned at start of file.</td>
<tr>
<td>w<td>Write only access. Pointer is positioned at start of file. File is created if it does not already exist.</td>
<tr>
<td>w+<td>Read and write access. Pointer is positioned at start of file. File is created if it does not already exist.</td>
<tr>
<td>a<td>Write only access. Pointer is positioned at end of file. File is created if it does not already exist.</td>
<tr>
<td>a+<td>Read and write access. Pointer is positioned at end of file. File is created if it does not already exist.</td>
<tr>
<td>x<td>Create and open for write only. Pointer is positioned at start of file. Return ''false'' if file already exists.</td>
<tr>
