When you log onto a Unix computer, the files you first see are located in your home directory. You can always return to your home directory by using the command
> cd ~  
  
> pwd  
  
/disk/username/
> ls  
  
 
Mwm				a.out* 			eqns2.ms  		public-html/ 	sample.doc 
README.first 	development/ 	plotoutfile.ps 	s2 
Here the * after a.out indicates that it's an 
executable file, the / after public-html and 
development indicates that they are directories containing yet 
more files, while the files with suffixes are plain files.  Note that the 
* and / are not part of the actual names 
of these files, and so should not be entered when typing commands.  (Note, 
too, that if your list command does not add on these cute little suffixes, 
we'll show you how to change that with an option or an alias.)
