Commands for moving around the file system include the following:
pwd: The pwd command will allow you to know the directory in which you're located (pwd stands for "print working directory").
For example, pwd in the desktop directory will show ~/Desktop. Note that the GNOME Terminal also displays this information in the title bar of its window. See the example presented in Figure A-1.
cd: The cd command will allow you to change directories. When you open a terminal you will be in your home directory. To move around the file system you will use cd. For example, cd ~/Desktop will move you to your desktop directory.
To navigate into the root directory, use cd /
To navigate to your home directory, use cd~
To navigate up one directory level, use cd ..
To navigate to the previous directory (or back), use cd -
To navigate through multiple levels of directory at once, use cd / var/www for example, which will take you directly to the /www subdirectory of /var/.
