+<code>pwd</code> (abbreviazione dalla lingua inglese di print working directory, stampa la directory corrente) è un comando dei sistemi operativi Unix e Unix-like,
 e più in generale dei sistemi POSIX, che mostra sullo standard output il pathname assoluto della directory corrente.
 Since a command line interface cannot provide graphic pictures of the file system structure, it must have a different way of representing it.
 Think of the file system tree as a maze, and you are standing in it. At any given moment, you are located in a single directory.
 Inside that directory, you can see its files and the pathway to its parent directory and the pathways to the subdirectories of the directory in which you are standing.

 The directory you are standing in is called the working directory. To find the name of the working directory, use the pwd command.
