It opens filel and file2 which have already been created with:rm filel; rm file2; touch filel; touch file2;echo "ghi" > filelecho "gst" > file2Therefore, each file contains 4 bytes.Here is the program (it will not compile as is because it contains a question mark):/* problem7.c */#include cunistd.h>int main(void){char buffer = 'W';open("filel", 2);open("file2",2);1seek (3, ?,1);write(3,8buffer, 1);1seek(4, -2,2);write(4, 8buffer, 1);read (e, &buffer, 1);write(4,8buffer, 1);1seek(3, -3,2);write(3, &buffer, 1);write(4, "\n", 1);1seek(4,1,0);write(4, &buffer, 1);close(3);close(4);Without a further header file compilation will produce a warning, but this will not affect this problem.When you enter a certain character and the single question mark is replaced with an appropriate number cat filel produces:gxiand cat file2 produces:gxWxWhat is that number and what is that character?The single question mark (?) should be replaced with:

Python script that uses the os module 1. Display the current working directory. 2. Create a new directory called "test_dir" in the current working directory. 3. Change the current working directory to "test_dir". 4. Verify the current working directory has been changed. 5. Create a new file named "test_file.txt" in "test_dir". a. You must write the following contents to test_file.txt: This is a test file. 6. Verify that "test_file.txt" was created by listing the contents of "test_dir". 7. Display the file size and the last modification time of "test_file.txt". 8. Change the name of "test_file.txt" to "new_test_file.txt". 9. Verify the name change by listing the contents of "test_dir" again. 10. Finally, remove "new_test_file.txt" and "test_dir", verifying each deletion by listing the contents of the parent directory.

When you change the data in a file that is hard-linked to three others, _____________.a. only the data in the file you modified is affectedb. only the data in the file you modified and any hard-linked files in the same directoryare affectedc. the data in the file you modified and the data in all hard-linked files are modifiedbecause they have different inodesd. the data in the file you modified as well as the data in all hard-linked files are modifiedbecause they share the same data and all have the same inode and file size
You have redirected Standard Error to a file called Errors. You view the contents of thisfile afterward and notice that there are six error messages. After repeating the procedure,you notice that there are only two error messages in this file. Why?a. After you open the file and view the contents, the contents are lost.b. The system generated different Standard Output.c. You did not append the Standard Error to the Error file, and as a result it wasoverwritten when the command was run a second time.d. You must specify a new file each and every time you redirect because the systemcreates the specified file by default.

Please read. It's Java. Write a client program and server program. The server uses a socket connection to allow a client to supply a filename and the server will send the file contents to the client or an error message if the file does not exist. The client will create a new file with the same contents. The client will supply the filename "input.txt" to the server and create as it's output "output.txt". Don't ask the user for these names. The Server sends whatever file the Client requests. Don't put "input.txt" in the Server. The client must get the contents from the Server. It must not read input.txt directly. Do not accept arguments from the command line. One class named Server and one named Client. These must be the ONLY 2 CLASSES
Which of the following operations should only be allowed to be done when the CPU is in kernel mode? Group of answer choices 1) Read data from a file 2) Open a file for reading, writing, or both 3) Set the time-of-day clock 4) Read the time-of-day clock A programmer opened a file using the file descriptor fd. The file contains the following sequence of bytes: 12, 14, 33, 33, 33, 12, 14, 1, 6, 33, 12, 14, 1, 6, 12 The programmer then uses these two system calls: lseek(fd, 3, SEEK_SET); read(fd, &buffer, 4); note, the lseek call makes a seek to byte 3 of the file. What does buffer contain after the read system call completes?
