To specify the absolute pathname, start with a single slash for the root. Then append the names of all directory nodes from the root to the desired file, adding another slash after each directory name. Finally, append the file name itself. For example, the absolute pathname of the file testfile, which is a child of directory myDir, which is a child of the directory anotherDir, which is a child of the root directory is: /anotherDir/myDir/testfile.
You can also refer to a file by its relative pathname by giving
the path from your current position in the tree to the place where
the file is. You go up one level in the tree by entering :
For example, if you are currently in the directory myDir and you want to find a file testfile1 in the directory yourDir, which is also a child of directory anotherDir, then the relative filename is: ../yourDir/testfile1
