<P><FONT SIZE="+1"><B><I>PURPOSE</I></B></FONT></P>

<P>The <B>xwd</B> command creates a screen capture of a screen or a portion of a screen to file. From there it can be printed or converted to another file format. After running this command, the cursor changes to a small crosshair icon; place the cursor over the window to be captured and press the left mouse button. Placing the cursor over the screen background or the root window will capture the entire screen. System sounds indicate the beginning and end of the screen capture.</P>
