<h2>Description</h2>
|
|
<p>
|
|
<code>PWD</code> (abbreviation of print working directory, it gives you the
|
|
corrent directory) it is a command of the operation system Unix and Unix-like,
|
|
and in general of the systems POSIX, that show on the standard output the
|
|
absolute pathname on the corrent directory.
|
|
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.
|
|
</p>
|
|
<p>
|
|
The working directory is the directory where you are standing in. So for
|
|
knowing where you are, you must use the pwd command.
|
