cat Command
cat (concatenate) command is an exceptionally versatile command.  First
let's look at a familiar use, viewing.  To use the cat command to
view a file simply type  cat  followed by the filename.  Try: 
> cd ~  
  
> cat .forward  
  
  
If you created your .forward file in the e-mail section, Unix should
display your e-mail address
Although cat, view and more can all be
used to view files, it is recommended that you only use cat for
very short files and use view or 
more for longer files.
Cat in combination with the special symbols <, 
>, >> and | can be used for several
other purposes which you will learn about over the 
next several sections.
