- For a UNIX program in C++, write a code segment to get the HOME directory, set PREVDIR to the current working directory, and then change the working directory to the HOME directoryWrite Linux commands for the following:i) To change the name of the existing file.ii) To show the current working directory.iii) To go one level up in the directory structure.iv) To change directory.v) To accept parameters at the command line rather than hard coding them withinthe program.Write a program that prompts the user for a path and displays the directory structureon the command tool as follows:
- What exactly is the Copy to Output Directory property?In a UNIX-like file system, a directory typically contains: A. filenames and i-nodes B. permission information, pointers to direct blocks C. filenames and ownership information D. filenames, i-nodes, major device numbers and minor device numberssd1, a subdirectory of the current directory, has a file called thefile. Move the file to another (already existing) subdirectory of the current directory called sd2 (keeping the same file name).
- Does a Master file containing persistent data have any value?Write a c program that list all files in a directory and subdirectory. For all the directories listed in the command line.Exercise 1: Please create a script that print “Hello, your name.” • Exercise 2: Please create a directory call user_bin, and add it to PATH. Then mv script of Exercise 1 to user_bin. Then run it from your root directory.• Exercise 3: Add a new command call ‘l’ which will perform exact same as ‘ls -a’. • Exercise 4: Create a function call sortFile, which will sort all filenames of current directory. Exercise 6: Could you add one variable in the example, name the variable as greeting, which displays “Hello, my name is xxx xxx” in the body using variable greeting
