CompTIA Linux+ 2014 Powered By LPI: LX0-103: GNU and Unix Commands

Administrators or advanced Linux users who will need to manipulate the operating system configuration or data files/directories from the command line


Expected Duration
118 minutes

A Linux distribution is made up of a number of utilities and programs. One key utility is the command line shell. In this course, you will learn how to use a shell to perform file and directory manipulation and edit file contents. In particular, you will learn about the Bourne-again Shell (bash) and the VI text editor. This course is one of a series in the Skillsoft learning path that covers the objectives for the CompTIA Linux+ exams LX0-103.


Work on the Command Line

  • start the course
  • perform single line shell commands and command sequences
  • use and modify the shell environment
  • use and modify the shell environment by defining, referencing, and exporting environment variables
  • use and edit the history of the Bourne-again Shell (bash)
  • use commands in the shell that are defined inside, and outside, the defined path

Perform Basic File Management

  • use shell commands to copy, move, and remove individual files
  • use shell commands to copy, move, and remove individual directories
  • use a single shell command to copy multiple files
  • use a single shell command to copy directories, and their sub-directories, recursively
  • apply wildcards to shell commands to filter files or directories that should be included
  • use the find command to locate and act on files based on the file type, size, or time
  • use commands to compress and decompress files
  • use the tape archive, or tar, command to create and extract archived files and use the built-in gzip or bzip2 parameter to compress or decompress the archive
  • describe how and when to use cpio to copy archives and dd to make and write image files

Use Streams, Pipes, and Redirects

  • describe how standard input, or stdin; standard output, or stdout; and standard error, or stderr, can be used to redirect output from a Shell command
  • use pipes to direct the output of one command to the input of another command
  • use the output of one command as arguments to another command
  • use tee or redirection to send the output of a single command to the standard output, or stdout, and a file

Perform Basic File Editing Operations using VI

  • use VI to open or create a document and move around within the document without using a GUI interface
  • use the basic VI modes to insert, add, and delete characters from a document as well as add lines to the document
  • use the VI commands to exit, cancel changes, and save changes to a document
  • use advanced features of VI to copy, paste, substitute, and move characters or lines within a document
  • use the search capability of VI to find text, and describe the basic use of patterns in searches

Practice: GNU and Unix Commands

  • navigate and search files using GNU and Unix commands
