UNIX tips:

  • Ever wonder where you are? That is, what directory you are in? Try the following command: pwd
  • The command to list files in the current directory is ls. To see more information about your files than just names, try adding the switch -al. That is type at the command prompts ls -al (the hyphen is important, and comes after a space). Now you see the size of the file, and even when it was last modified!
