In Linux with chmod, you can change permissions for a specific level of users add the execution bit for the group and leave all the rest unchanged True or False

In C Programming Add a new built-in path command that allows users to show the current pathname list, append one pathname, or remove one pathname. 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…

Define the term exception.

write c programming in raspberry pi # Write the command to copy the information from info.txt to the text files in each folder test01 to test10 # start i=1 while i<=10 do (i++) cat info.txt >> ./test$i/test$i done #end Does the script run as expected and without errors?

PROGRAM DESCRIPTION:In this assignment, you will write two complete C programs to support a client/server model using Linux sockets for a UDP “ping” utility, similar to the ping utility already available on our CSE machines. Servero The server program will be called with one command-line argument, the port number being used, such as ./minor4svr 8001. If the user calls the server program with too few or too many arguments, you will print out a usage statement and terminate the program.o The server will set up a UDP socket on the Internet (i.e., INET) domain and then wait in an infinite loop listening for incoming UDP packets, specifically PING messages from a client.o Packet LossUDP provides applications with an unreliable transport service. Messages may get lost in the network due to a variety of reasons. Since packet loss is rare or even non-existent in typical campus networks, the server in this lab will inject artificial loss to simulate the effects of network packet loss. The…
