Compression Process to use for CSE 222

Create a Tarred and Zipped Directory --   To create a zipped directory (for project submission) use the following command, where "name" is your last name, "N" is the mini-project number, and "name_mpN" is the directory to compress, a sub-directory of your current directory:

   tar -cvzf name_mpN.tgz name_mpN

List Contents of Compressed Directory --   To list the contents of a downloaded directory run the following command:

   tar -tzf file.tgz

Uncompress Downloaded Directory --   To uncompress a downloaded directory, run the following command in the directory where you would like the new subdirectory to be located:

   tar -xzf file.tgz

Other How To's --  

• Secure shell login and data copy via the sshd "daemon" --

  1. Remote login via a secure shell (ssh) --

        ssh ID@pi.nmt.edu
     

     You will be prompted for the password for the remote host.

  2. Remote login via a secure shell (ssh) allowing secure data X-windows to be placed back on the local screen --

        ssh -X ID@pi.nmt.edu
     

     You will be prompted for the password for the remote host.

  3. Copying a file to a remote system via a secure copy (scp) --

        scp LocalFilePath ID@pi.nmt.edu:DestinationDirectoryPath
     

     You will be prompted for the password for the remote host.

  4. Copying a directory to a remote system via a secure copy (scp) --

        scp -r LocalDirPath ID@pi.nmt.edu:DestinationDirectoryPath
     

     You will be prompted for the password for the remote host.

  5. Copying a file from a remote system via a secure copy (scp) --

        scp -r ID@pi.nmt.edu:RemoteFilePath LocalDestinationDirectoryPath
     

     You will be prompted for the password for the remote host.

  6. Copying a directory from a remote system via a secure copy (scp) --

        scp -r ID@pi.nmt.edu:RemoteDirPath LocalDestinationDirectoryPath
     

     You will be prompted for the password for the remote host.
