Where the heck am I?
pwd
To move up one directory:
cd ..
To move up two directories:
cd ../..
To go back to your home, from anywhere:
cd
or
cd ~
Note that the tilde ( ~ ) means “home,” and is relative for every user.
Of course, you can always specify your destination:
cd /home/studenth/
Or go back to the immediately previous directory:
cd –
