A file named abd.txt has the following set of permissions -rwxrwxrWX All the three operations i.e read, write and execute can be performed on the file by file owner, group owner and others. a) True b) False13. After you define a file pointer, you can connect that pointer to a file with fread () fopen ( ) fseek () fprintf ( ) a. b. С. d.9- Using sed command, we're able to quickly and easily find and replace a set of characters within a file. sed command uses extended regular expression to define the pattern that should be replaced. sed -i 's/original/new/g' file.txt Explanation: sed = Stream EDitor -i = in-place (i.e. save back to the original file) • The command string: s = the substitute command • original = a regular expression describing the word to replace (or just the word itself) new = the text to replace it with 3D g = global (i.e. replace all and not just the first occurrence) file.txt = the file name If we have a file named hello.txt, write a sequence of sed commands that replaces the following all occurrence of the word bad with the word good. b) all integer numbers by the word Zero hello.txt The description of the items 512 are good 90 are bad 44 are excellent 123 67 309

In an earlier assignment, you created a fileAsst directory containing several files. Give a command that will create a file named listing.dat, in your current (commandsAsst) directory, containing a list of the names of all the files in your fileAsst directory. The listing must not include dates, file sizes, or any information other than the names. 2. Someone has decided that the function sequentialInsert, declared in -cs252/Assignments/commandsAsst/project/arrayops.h, should be renamed orderedInsertion. Give a command to produce the altered version the header file, saving it as ~/UnixCourse/commandsAsst/arrayops.h (Something to think about: Why would the same approach not work well for changing the variable name i to i0?) 3.

- When a Python program begins execution, it creates three standard file objects: ● sys.stdin–the standard input file object, ● sys.stdout–the standard output file object, and ● sys.stderr–the standard error file object. You must import the sys module if you need to refer to these objects explicitly in your code, but this is rare. Which of the following statements is false? Function print implicitly outputs to sys.stdout, which appears in the command line. The input function implicitly uses sys.stdin to get user input from the keyboard. Python implicitly outputs program errors and tracebacks to sys.stdout. Though these are considered file objects, they do not read from or write to files by default.Entry point for the application. Exactly zero or one command-line argume\nts are expected. * If a filename is given as an argument, then the program should print the\ contents of that * file to standard output. If a single dash (i.e., "-") is given as an arg\ument, then * the program should print the contents of standard input. * * @param args the command-line arguments */Please in C Language (CYBER SECURITY) Write a program that uses an existing text file (text.txt) to determine the number of occurrences of each letter.
