/home/anthoniraj

I am using home directory , here anthoniraj is the user of the system. Now i want to change home directory to “/opt”

anthoniraj@Ubuntu:~$ cd /opt/

anthoniraj@Ubuntu:/opt$

You can also use dot (.) for changing directory

anthoniraj@Ubuntu:/opt$ cd ..

anthoniraj@Ubuntu:/$ pwd

/

[/ - root directory]
