Question
Hi, could help find the error in my code please. here what the exercise ask:
- Name the script args.sh.
- The script will take any number of command line arguments.
- The script will print (echo) each of the command line arguments on its own line, and will then print the total number of arguments entered.
- You should use the special shell variables. One special variable contains all the command line arguments. There is another one that contains the number of command one arguments entered.
- This script is most easily completed with a for loop, although the task can also be accomplished with a while loop, but you definitely need some type of loop since it has to process an unknown number of command line arguments.
This is what i have put so far:
I am stuck because in this way, i don't know how to sum up and calculate everything. maybe some help?

- Which of the following are true with respect to the functionality provided by scanf and printf? Choose ONLY the correct options (one or more). Question 7 options: Although printf is not passed the pointer to an integer variable, it can still access the original integer variable's memory location to read its contents. None of the other options given are true. scanf needs to be passed the pointer to an integer variable because it needs to modify the original variable. scanf's functionality can also be implemented so that it can be given the original integer variable directly without having to pass its address.arrow_forwardI am looking for the following in your program: Python GUI-based MP3 Player Project #3: Python GUI-based MP3 Player 1.

It is not to be executed like other programs the user types in. If the exit command is on the same line with other commands, you should ensure that the other commands execute (and finish) before you exit your shell. These are all valid examples for quitting the shell: prompt> exit prompt> exit; cat filel prompt> cat filel; exitarrow_forward

- In this assignment, you will implement the shell “engine” as the “group” component, where all members are responsible for the following functionality: • A Command-Line Interpreter, or Shell Your shell should read the line from standard input (i.e., interactive mode) or a file (i.e., batch mode), parse the line with command and arguments, execute the command with arguments, and then prompt for more input (i.e., the shell prompt) when it has finished. 1. Interactive Mode In interactive mode, you will display a prompt (any string of your choosing) and the user of the shell will type in a command at the prompt.arrow_forwardHi, I need to solve this problem with C++ programming language using Visual Studio.
