Observations
Step 1:
- This program executes code that is the equivalent of the command line code: "ls | sort" using pipes for IPC.
- "ls | sort" displays the contents of the current directory in alphanumeric order.
Step 2:
- This program sends cmd line arguments from one process to another process for output using pipes.
Step 3:
- This program sends the output of the "ls" command from one process to another for output using pipes. It is a modification of the program from step 2.
Step 4:
- This program executes code that is the equivalent of the command line code: "cat /etc/passwd | grep root" using pipes for IPC.
Step 5:
- This program is an example of the producer-consumer problem using pipes.
