Hands-on Lab #3

Working with Files

Using the UNIX command line interface, properly view contents in files and use the proper commands to create, find, copy, rename, move and delete files. Do this for multiple files and get accustomed to file manipulation in UNIX.

IV. Text Manipulation - Using a Crucial Power-User Tool

The editor in UNIX is your key power user tool. In this section you will learn the details of the“vi” editor and get hands-on experience using it to edit files. Additionally, you will get a snapshot view of "sed" and "akw" and will use these commands hands-on based on your needs as a power user.

1. A. Types of editors
2. B. The “vi” editor
   • Starting and quitting a vi session
   • Saving the modified edit buffer to a file
   • Copying, cutting and pasting Test
3. Customizing your “vi” session
4. Text processing utilities
   • “sed”-stream editing and“awk” field processing
     

Hands-on Lab #4

Links

Learn how to create a file that refers or points to an object, called links. Create hard links and symbolic/soft links and verify the results.

V. File Security - Valuable Protection Strategies

Protecting files and providing file level access is one of the most common operations in any operating system. UNIX file level security is an important aspect of its capabilities. You will learn all aspects of UNIX file permission structure and how to work within that structure.

1. A. File permissions
   • Changing file permissions
2. B. Default permissions
3. C. Ownership and groups
   
   

Hands-on Lab #5

Using Editors and Text Processing Utilities

Use the “vi” editor to create and modify multiple files. Use “awk” and“sed” to reformat the contents of a file.

VI. Input and Output to Files and Commands

Execute “stdin,” “stdout,” and“stderr” and learn how to modify the output of several commands.

1. File descriptors
2. File redirection
3. The “Bit Bucket”
4. Using Pipes to connect processes via I/O

Hands-on Lab #6

Redirections and Pipes

Use and execute a combination of redirection and pipes to modify the output of several commands. Use the /dev/null file for unwanted output.

VII. The Shell - Interfaces that Work

UNIX uses the concept of a shell to provide both a command and a programming language that provides an interface to the UNIX operating system. Learn about different Shells available and their capabilities. Also see how shell programs combine the operating system's small commands to accomplish larger tasks.

1. sh, csh, and ksh
   
2. Shell variables
