In your shell implementation, you may keep a data structure to deal with the pathname list. If you do not use execle() or execve() that allows you to execute with your own environment variables, you will need to add it to the “real” PATH environment variable for executables in the path to work correctly. The initial value of path within your shell shall be the pathname list contained in the PATH environment variable. Implement the path command as follows: • path (without arguments) displays the pathnames currently set. It should show pathnames separated by colons. For example, "/bin:/user/bin". • path + ./bin appends the pathname to the path variable. You may assume that only one pathname is added at a time. • path - ./bin removes the pathname to the path variable. You may assume that only one pathname is removed at a time. You may assume…Write a php page(login.php) that reads a user ame and a password. When the user presses the login button, the username and password will be stored in an ACCESS database.

- The Linux operating system is a very popular server OS. A network administrator has to protect the login/password files stored on the servers. In Linux there are two important files: /etc/passwd And it contains rows that look like this: root:x:0:0:root:/root:/bin/bash bin:x:1:1:bin:/bin:/sbin/nologin daemon:x:2:2:daemon:/sbin:/sbin/nologin adm:x:3:4:adm:/var/adm:/sbin/nologin ftp:x:14:50:FTP User:/var/ftp:/sbin/nologin user1:x:15:51:User One:/home/user1:nologin user2:x:15:51:User One:/home/user1:nologin user3:x:15:51:User One:/home/user1:nologin This file contains login information. It's a list of the server's accounts that has userID, groupID, home directory, shell and more info.

Backups of the customers’ details are done on a spreadsheetdocument stored on Google drive. However, anyone who has access to the Google drive link ofthe file can view and modify all the customer details. On the backup, the system administratordoes not have visibility of the modifications made on the file. By analysing the scenario above, use the security design principles to criticise theoperations of the small insurance company and propose any two simple controlsthat could influence a good security program.Need help to implement networking in python Server.py Load data from file This option will ask the user for a fully qualified path and will load a JSON file containing the information for users and pending messages.

- In UNIX-based operating systems, opening a file using a file handle can be done only in the kernel. Give a possible implementation of an NFS file handle for a user-level NFS server for a UNIX system.Scenario: You have been tasked with building a URL file validator for a web crawler. A web crawler is an application that fetches a web page, extracts the URLs present in that page, and then recursively fetches new pages using the extracted URLs. The end goal of a web crawler is to collect text data, images, or other resources present in order to validate resource URLs or hyperlinks on a page. URL validators can be useful to validate if the extracted URL is a valid resource to fetch. In this scenario, you will build a URL validator that checks for supported protocols and file types.Kindly help me with this python program write a system to support sending and receiving of quotes.

This file records the access a user makes when visiting a web page (like this one!). Each line the log has the following items: • a host (e.g., '146.204.224.152') a user_name (e.g., 'feest6811' note: sometimes the user name is missing! In this case, use '-' as the value for the username.) • the time a request was made (e.g., '21/Jun/2019:15:45:24 -0700') • the post request type (e.g., 'POST /incentivize HTTP/1.1' note: not everything is a POST!)

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…
