- UNIX ASSIGNMENT - IXQuestion 8 : Rename all the files within a folder with suffix “CS_” i.e. suppose a folder has two files file_a.txt and file_b.pdf than they both should be renamed from a single command to CS_a.txt and CS_b.pdfWe will use the file classlist.txt. Note that it contains a list of usernames. 3. Write a script called finduser that is to be called as follows, where classlist is the name of the classlist file, and username is a particular student's username, either first name or last time. ./finduser classlist username The script should check that the correct number of arguments was received and print an error message if not, check whether the classlist file exists and print an error message if not, print the line of the given username in the classlist file If you have not been doing so all along, you should now add some comments to your script and thoroughly test it! 4. Write the script into your lab report.Build a csharp application that reads from a file and print out the contents of that file in another files words by words (i.e. one word each line)
- Given a valid file object, f, which of the following calls will return the entire contents of the file in a scalar x? x = f.readline() x = f.readlines() x = f.read() X = read(f)Write a program that removes all the occurrences of a specifiedstring from a text file. For example, invokingjava Exercise12_11 John filenameremoves the string John from the specified file. Your program should get thearguments from the command line.This is for Advanced Java Programming Write a test program that reads words from a text file and displays all non-duplicate words in ascending order and then in descending order. - The file is to be referenced in the program, not needing to be used as a command line reference. - The word file is to be titled collection_of_words.txt and included in your submission. Write test code that ensures the code functions correctly.
- 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…Write a program FileSorter that takes the name of adirectory as a command-line argument and prints out all of the files in the currentdirectory, sorted by file name. Hint : Use the File data type.Write a program that removes all the occurrences of a specified string from a text file.
