Our next command is
cd, which stands for “change directory.” Just as you would click on a folder in Windows Explorer or Finder,
cd switches you into the directory you specify. In other words,
cd changes the working directory.
Let’s say the directory we change into is 2015/:
$ cd 2015
When a file, directory, or program is passed into a command, it is called an argument. Here the 2015/ directory is an argument for the
cd command takes a directory name as an argument and switches into that directory.
It is also important to move up one directory. For this, we use:
$ cd ..
.. stands for the directory above the current working directory. Assuming we are in /home/ccuser/workspace/blog/2015:
$ pwd /home/ccuser/workspace/blog/2015 $ cd .. $ pwd /home/ccuser/workspace/blog
The above example uses the command
cd .. to navigate up to the /home/ccuser/workspace/blog/ directory.
Our current working directory is /home/ccuser/workspace/blog/. Change into the 2015/ directory.
Confirm you are in the 2015/ directory using
Make sure to click the Check Work button once you’ve completed each checkpoint.
Now move back up to the blog/ directory using the
Confirm your location again with
pwd and click the Check Work button?
Let’s move further into the filesystem. We are currently in the blog/ directory. From here we want to move into the 2015/ directory, then into a directory named jan/ and lastly, a directory named memory/. (You can reference the filesystem for this lesson here.)
Move down the filesystem into the memory/ directory and print the working directory again to see the new location.
