- Assignment #3: Unix shell with redirects and pipes The purpose of this assignment is to learn to develop multi-process programs. You are expected to extend the myshell.c program and add pipelines and I/O redirections. In particular, your shell program should recognize the following: > - Redirect standard output from a command to a file. Note: if the file already exists, it will be erased and overwritten without warning. For example, COP4338$ ls > 1COP4338$ sort myshell.c > 2 Note that you're not supposed to implement the Unix commands (ls, sort, ...). You do need to implement the shell that invoke these commands and you need to "wire" up the standard input and output so that they "chain" up as expected. >> - Append standard output from a command to a file if the file exists; if the file does not exist, create one. For example, COP4338$ sort myshell.c >> 1COP4338$ echo "Add A Line" >> 1 < - Redirect the standard input to be from a file, rather than the…In this laboratory work, you are expected to write a c# console application to make someoperations about the customers. Operations and required featurest that you need to cover inyour program are following:• Add: This function adds a new person to json file. You need to get inputs from userand adds the new one into json file.• Display: This function displays all people in your json file.• Search: This function let you search with the user id.• Create Password: This function will create a random password for the user and usermay choose the length of the password. Password may include numbers andcharacters.• Exceptions: You need to handle exceptions as well. You should at least handle 3 ofexceptional cases. For the case that file can not be found, It is mandatory to catch theexception.In C++ can someone make a code where it prompts me to login. But it has to grab a txt file and reads user name and password separated with a comma and once inputted in a code it will let me know it was successful.
- #Linux Operating System#Powershell#Bash shell scriptHi guys i need bash shell script expert help.Write a shell script that reads a file name and checks this file exists or not.

- Please write in C++. Please look at the example and the example output.In UNIX, What is the difference between using +/- versus = when setting file permissions? Is there any benefit of using = instead of +/- to set permissions?The Shell or Command Line Interpreter is the fundamental User interface to an Operating System. Your task is to write a simple shell - myshell - that has the following properties: Tasks: The shell must support the following internal commands: cd <directory> - Change the current default directory to <directory>. If the <directory> argument is not present, report the current directory. If the directory does not exist an appropriate error should be reported. This command should also change the PWD environment variable. cls - Clear the screen. iii. dir <directory> - List the contents of directory <directory> page by page. xcopy <source> to <destination> - Copy the <source> folder to <destination>. print <comment> - Display <comment> on the display followed by a new line (multiple spaces/tabs may be reduced to a single space). md <directory> - Create the folder <directory>. vii. rd…
