4. More on File Systems(a) Discuss file systems used on Unix or Linux systems. There may be many different Unix vendors aloneand also Linux vendors alone. There also may be many many different file systems for Unix or forLinux. Generally we know that in Linux, a path uses forward slash such as /usr/lin.password, while inWindows, backward slash is used such as C:\\Temp\Lin. Find one or two current and hopefullydominant Unix/Linux file system and explain that .(b) Discuss file system(s) on McIntosh. It may be similar to Unix / Linux file system(c) Discuss file system(s) on Google Android.(d) Discuss file systems on IPhone / IPad. It may be similar to Mac, and maybe similar to Unix / Linux.

I have an issue with trying to modify my code, I need to instead to work such that a user imputs a file paths and the program synchronizes themthe code is too long to post so I have placed it belowhttps://github.com/Philanthropenos/2023-final-work-for-os-class/blob/main/Attempt1.1
Q7.Which of those mechanisms would probably work better for random file access?
Starting out with hadoop and I need to find the 8-bit XOR checksum of all bytes from 1000000000 till 1000000999 (inclusive) with the offset in a file called "bigdata" in a directory called d1. How would I do this in Java using the HDFS API?
The aim of this lab is to familiarize yourself with reading and processing directories aswell as extracting file attributes using the stat() system call. You are essentially writingyour own version of the long format of the ls command. You will need to customize youroutput to match the following specifications: -o: specifies the minimum age of the files (modification timestamp) to be listed fromthe target directory. The -o argument will be followed by an integer (as a separate parameter to make things easier if you wish). This integer will represent the minimumnumber of days old the files can be in order for them to be included in your listing.As an example "-o 3" passed as arguments would mean: list all files that have beenmodified more than 3 days ago (from the current system time).
Write a C program to remove an empty directory In this program it is required toread the name of the empty directory and Then need to remove the given empty directory using the system () function.
find The find command takes a pattern as a command-line argument and recur- sively searches through directories to find a filename matching that pattern. It should print a relative path starting with "./" for every file/directory that matches. For example, running ./find 1s.c from within the hw2 directory should print ./1s.c. If run from the parent directory, the output would be . /hw2/1s.c. There may be multiple matches. If we run ./find .c from within the hw2 directory, we should see: ./find.c ./1s.c ./tree.c The output does not need to be sorted. If nothing matches, it shouldn't print anything. Pattern matching should be case sensitive.
What would be the absolute pathname (for a Linux System) for a file name keybd located under the root directory’s “dev” subdirectory?
2. Exploring envp:a. Modify showEnvp.c so it reports envp addresses in the same style as showArgs2 displays argv addresses. Save a copy of the output in a file – you’ll need to refer to it in part b. Provide a program listing, a status statement and 6-8 lines of output, but not all the output. (2)b. Inside your program use putenv to define one environment variable and setenv to redefine another. Do these values appear in the array envp or __environ or both? (2)c. Based on the program output sketch a data structure diagram for envp. You only need to include the first 3 environment variable values (2) Hand in a commented listing of your program, proof of testing and a status report. On your cover page, aside from your name, the course code, lab section and the assignment #. Make sure you include your student number. If I have to look it up to verify that you are doing the correct exercise - 2 marks off. If you do the wrong exercise 2 more marks will be deducted showEnvp.c#include…
