Question

Create source code, compile it, and produce a script with test cases

demonstrating the correctness of the following programs:

1. Write a program in C using stat() which receives a file name on the

command line and displays on the monitor the correct answer to the

question of whether the user of the program is in the group of the owner of

the file.

2. Use a single pipe in a C program and create 3 child processes. Each child

process should prompt the user to enter a character and then writes it into

the pipe. The parent process should read from the pipe and display the

character with the largest ASCII value.

3. Create a shell script which displays on the screen the following data:

a. the current time and date

b. the id of the user

c. the full path name of the users home directory

d. a recursive list of all the files under the users home directory in

sorted order

3-You should use

mkdir "$(date +"%d-%m-%Y")"

cd "$(date +"%d-%m-%Y")"

In the extreme case a day passes between the first and the second statement, that won't work. Change it to:

d="$(date +"%d-%m-%Y")"

mkdir "$d"

cd "$d"
