GTU OS Program - 14 AWK program

14. Write an awk program using function, which convert each word in a given text into capital.

First of all what is awk ?

Awk is a utility that enables a developer to write small but effective programs in the form of statments. Using awk we can scan a file line by line, transform data files, compare input lines to a defined pattern, etc.

Complete code of the program

  1. read -p "Enter a lowercase String : " string
  2. echo "Resultant Upercase string is : "
  3. echo "$string" | awk '{print toupper($0)}'

Interpreting the upper.sh file and executing it in terminal

  1. tkanu025@hp:~/lab_solutions$ chmod +x upper.sh
  2. tkanu025@hp:~/lab_solutions$ ./upper.sh

GTU OS Program - 11 Filters

Image
11. Shell programming using filters (including grep, egrep, fgrep). The programs that take plain text as standard input and transforms it into a meaningful format, and then returns it as a standard output is known as Filters. Some of the most commonly used filters are explained below: cat head tail sort uniq wc grep tac sed nl 1. cat: Displays the text of the file line by line. Syntax cat [path] Output 2. head: Displays the first n lines of the specified text files. If the number of lines is not specified then by default prints first 10 lines. Syntax head [-number_of_lines_to_print] [path] Output 3. tail: It works the same way as head, but in reverse order. It returns the lines from bottom to up Syntax tail [-number_of_lines_to_print] [path] Output 4. sort: sorts the lines alphabetically by default but we can customize the ...

Note:Due to some reason .gif files were not supporting in my program so instead of .gif images I have used .jpg format images of O and X. import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.image.Image; import javafx.scene.image.ImageView; import javafx.scene.layout.GridPane; import javafx.scene.layout.VBox; import javafx.stage.Stage; public class Program_17 extends Application { @Override public void start(Stage primaryStage) throws Exception { primaryStage.setTitle("Tic-Tac-Toe by kt"); GridPane gridPane = new GridPane(); for (int i = 0; i < 3; i++) { for (int j = 0; j < 3; j++) { int n = (int) (Math.random() * 3); if (n == 0) gridP...
