findThe find command takes a pattern as a command-line argument and recur-sively searches through directories to find a filename matching that pattern.It should print a relative path starting with "./" for every file/directorythat matches.For example, running ./find 1s.c from within the hw2 directory shouldprint ./1s.c. If run from the parent directory, the output would be . /hw2/1s.c.There may be multiple matches. If we run ./find .c from within thehw2 directory, we should see:./find.c./1s.c./tree.cThe output does not need to be sorted. If nothing matches, it shouldn'tprint anything. Pattern matching should be case sensitive.

A student launches the Python interpreter from his home directory. His home directory contains another directory called 'mydir', and 'mydir' contains two files called 'foo' and 'bar'. The home directory does not contain any files, only other directories. What will happen when he writes the following code at the Python prompt: >>> import os >>> filenames = os.listdir('mydir') >>> f= open(filenames[0]) ===================================================================================== A variable f representing a file object will be created, and the first file in the directory 'mydir' will be opened for writing in text mode. An error will be produced stating that the file to be opened does not exist. An error will be produced stating that filename is not subscriptable. A variable f representing a file object will be created, and the first file in the directory 'mydir' will be opened.
In C++ Implement a simple version of the linux grep command in C++. grep - Looks through a file, line by line, trying to find a user-specified search term in the line. If a line has the word within it, the line is printed out, otherwise it is not. Use the system calls open(), getline(), close(). Requirements (examples run from. terminal) Your program grep is always passed a search term and zero or more files to grep through (thus, more than one is possible). It should go through each line and see if the search term is in it; if so, the line should be printed, and if not, the line should be skipped. [terminal]$ ./grep ! main.cpp main2.cppcout << "Hello, World!";cout << "Programming is great fun!"; The matching is case sensitive. Thus, if searching for world, lines with World will not match. Lines can be arbitrarily long (that is, you may see many many characters before you encounter a newline character, \n). grep should work as expected even with very long lines. For…
Please in C Language Write a program that uses an existing text file (text.txt) to determine the number of occurrences of each letter. You can assume that the file is filled with only lowercase letters and only the letters from a-z are present! Write the result in a new file to be created by the program! Errors when opening and closing the files must be caught!
Write a program called asyncFileCount.js that prints the number of files with a given extension in a given directory. The first argument will be the path to the directory we want to filter on (e.g. /path/to/dir/') and a file extension to filter by as the second argument. For example, if you get '.txt' as the second argument then you will need to filter the list to only files that end with .txt Below are some example runs: An example run would be: node asyncFileCount.js . .js Another example run would be: node asyncFileCount.js /Users/jalirani/Desktop .docx
Unix-based operating systems usually include a tool named tail. It displays the last 10 lines of a file whose name is provided as a command line argument. Write a Java program that provides the same behavior i.e. the user can specify how many lines to print from the terminal. Display an appropriate error message if the file requested by the user does not exist, or if the command line argument is omitted. Note: Make sure to display the last n lines of a file whose name is provided as a command line argument. You might need to pass a file as an argument, therefore make sure to have access to a sample file, the contents of which you want to print out.

Suppose you have Java source files under the directorieschapter1, chapter2, . . . , chapter34. Write a program to insert thestatement package chapteri; as the first line for each Java source file underthe directory chapteri.

If wrong answer this time will downvote it Create a class with a static main that tests the ability to resolve and print a Path: • Create an instance of a FileSystem class. • Resolve an instance of a Path interface from a directory path and filename. • Print the constructed Path with System.out.println() method. 2. Create a class with a static main that tests the ability to resolve and print a Path: • Create an array of Path class. • Instantiate instances of Path with absolute and relative paths. • Print the constructed elements of the array of Path class with System.out.println() method. 3. Create a class to test serialisation class that implements serializable, it should implement the following: • A static void method that serialises an object. • A static void method that deserializes an object. • A static main method that tests the two by moving an object from one to the other
Write a program that opens a text file (name the textfile “problem4.txt”) and reads its contents into a queue of characters. The user must then enter a character they are looking for. The program should then dequeue each character and count the number of characters that are equal to what the user is looking for. Output the count of the character or lack thereof in a second file (name the textfile “resultsp4.txt”). in C++
