Tutorial

  • Tutorial 1: Log in to the system(credentials in the board), open the Terminal and type the following on the login prompt :

    • echo hello world

      • The wordhello worldwould get displayed as an output on the terminal. The echocommand displays a line of text, type man echoto read what an echo command does.

    • Linux provides on-line manuals for different commands through an interface called man.

      • To know about man type the following on the terminal: man manand read the description that is displayed.

      • For all commands, we will use the syntax

man <command name>

      • This prints /bin/bash

      • bash is the name of the login shell that is currently in use

    • Study the following Unix/Linux general-purpose utility commands using their man pages and execute them on the terminal :

      • man, who, cat, cd, cp, ps, ls, mv, rm, mkdir, rmdir, echo, date, time, kill, chmod, chown, pwd, cal

  • Tutorial 2: Study the following Linux commands: sed, grep and awk

    • Use the grep command to find how many lines of a word in the given word. The filename and the word are provided as inputs.

  • Tutorial 3: Shell scripting

    • Write a shell script to display “HELLO WORLD” on the terminal :

      • Open an editor

      • Type echo HELLO WORLD

      • save the file with .sh extension ( say test.sh)

      • close the editor
