Unix for your gl account

Tutorial1

• You need to learn how to logon to your umbc gl account. You use an SCP client (FTP also works but is not preferred) to transfer files to your account from your PC and you use an SSH client to get command-line access to your gl account.
• You need to learn these unix commands that you can use up on your gl account at the command-line.
  • Use this tutorial one for the commands.

  ls	list files and directories
  ls -a	list all files and directories
  mkdir	make a directory
  cd directory	change to named directory
  cd	change to home-directory
  cd ~	change to home-directory
  cd ..	change to parent directory
  pwd	display the path of the current directory

  • See also the tuorial five (5.1 and 5.2 only) for ls -l and chmod.
• Also be sure to learn ssh, scp, and the nano text editor. Ask any questions on the forum.
• Another handy command is wget. It allows you to get a file using HTTP from a web server from the command line.
