Nikhil and Commands

Nikhil learnt two new commands pwd and cd on the first day of Operating Systems lab. pwd - command displays the current working directory and, cd - changes the location of working directory. If the cd parameter contains ".."(without quotes), that means to step one directory back. The absolute path of directory is separated by slashes "/"(without quotes). The default root directory is "/".
