Working with NFS files

Files saved on the UITS central Unix computers Steel, the Parallel PC cluster, Solar/Lunar, and the Research SP are stored on the Network File Server (NFS). That means that your files are really on one disk, in directories named for the central Unix hosts on which you have accounts.

No matter which of these computers you are logged into, you can get to your files on any of the others. Here are the commands to use to get to any system directory from any other system:

  cd /N/u/username/PPPC/
  cd /N/u/username/Cobalt/
  cd /N/u/username/Solar/
  cd /N/u/username/Steel/
  cd /n/u/username/SP/

Be sure you use the capitalization just as you see above, and substitute your own username for "username".

For example, if Jessica Rabbit is logged into her account on Steel, and wants to get a file on her SP account, she would enter:

  cd /N/u/jrabbit/SP/

Now when she lists her files, she'll see her SP files, even though she's actually logged into Steel.

You can use the ordinary Unix commands to move files, copy files, or make symbolic links between files. For example, if Jessica Rabbit wanted to move "file1" from her Steel directory to her SP directory, she would enter:

  mv -i /N/u/jrabbit/Steel/file1 /N/u/jrabbit/SP/

This shared file system means that you can access, for example, your SP files even when you are logged into Steel, and vice versa. However, if you are logged into the SP, you can only use the software installed on SP -- only users' directories are linked together, not system directories.
