- The superblock in a Linux file system is important because : O it holds all of the inodes O it contains all file system configuration parameters it is owned by the superuser O it is managed by the superintendentLinux: The file located in /etc/X11/ that stores the configuration information for X.org is ...In UNIX/Linux, what would the octal notation be for a file with the following permissions:. • Owner can read, write, and execute • Members of the group can read and write • Members not belonging to the above can only read
- In linux: Identify the various fields of information ls -l output gives for a file.What are the basic differences between the ways in which the Windows and Linux file systems are organized?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…
- C++ Part 1: Working With Process IDs Modify the getProcessID() function in the file named Processes.cpp The function must find and store the process's own process id The function must return the process id to the calling program. Note that the function currently returns a default value of -1.Hint: search for “process id” in the “System Calls” section of the Linux manual. Take a screenshot of a sample output and upload the picture as part of your assignment submission. Part 2: Working With Multiple Processes Modify the createNewProcess() function in the file named Processes.cpp as follows: The child process must print the message I am a child process! The child process must then return a string with the message I am bored of my parent, switching programs now The parent process must print the message I just became a parent! The parent process must then wait until the child process terminates, at which point it must return a string with the message My child process just…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?What are the tools available on Linux systems to help youunderstand and manipulate object file ?
- If we do not specify the executable file name at the compilation time in GCC, then in linux the compiler creates executable named as a.out a.exe x.out x.exe1) Create a daemon in C in the Unix environment, your daemon must create a text file called aitDaemonLog.txt and populate it with 1000 lines of a string each line must be written after 10 seconds, the string must end with the count of the string;. 2)Create a shell script that lists all the files in the present working directory in long format name this file listMyFiles.sh. Write a c program that uses the system() function and uses it to run listMyFiles.sh 3)Write a c program to write a string of your own choosing into shared memory then read the contents of the shared memory created in 4)demonstrate in a c program how to use a fork to create a child process, using pipes let this child process send a message which is read by the parent process 5) Write a c program that shows the PID, PPID, UID and GID of a running process, let this process fork thus creating a child process, let the parent process count from 0 to 50 and the child process from 0 to 25 each process showing while counting…Hello! I have an assignment for my linux class and I am having some difficulty with the last question which was a challenge to me: Here is the last bit of homework CHALLENGE: Your job is to create a booklet (i.e. a printable file) that contains the name of every header file on the system followed by a 1-line description of the purpose of that file. (Hint: the first line of the .h file has a description). Each file name and description set should be followed by a blank line before the next file name entry in this file. Example file entry: (shown on picture attached) I am really desperate as I have tried everything it doesn't seem to go through.
