You can work in pairs on this lab if you wish. Otherwise work individually.
Login
- Login to a Linux box around you using your CSC220a account.
Question Group 1
- What is the path of your account? In other words, what subdirectories does one have to traverse to reach your account.
- What other subdirectories are at the same height as yours in the directory tree?
- You will notice that all user accounts are in a major directory called Users. The old standard for users on a linux system is to have the users in a directory called home in the root directory.
- You will notice that some user accounts still exist in home. Which are they?
Question Group 2
- With Linux, the name of the printers supported are listed in a file called /etc/printcap. Look at its contents.
- Figure out a way to get only the entries from this file that represent printers that are in Ford Hall.
Question Group 3
- Open a browser window and load up the following URL: http://maven.smith.edu/~hadoop/log.txt
- Notice that it is a long log of the output of a research program I have been running recently. It is very long and contains a lot of information: some useful, some not.
- You are going to get a copy of this file into your account. Instead of copying and pasting the text into a file, you are going to use a useful utility called wget. Wget is a Linux utility that allows you to grab Web pages from Web sites, without using a browser.
- Try it:
wget http://maven.smith.edu/~hadoop/log.txt
- Check that the file is in your directory
