Fork.c

myshell.c

myls.c

1. Carefully study the examples provided: fork.c, myls.c, myshell.c, etc.You need to know how they work in order for you to finish this assignment; the examples will also get you prepared for assignment 3. 2. Write a program called minishell that creates two child processes: one to execute 'ls -al' and the other to execute 'grep minishell.c'. After the forks, the original parent process waits for both child processes to finish before it terminates. The parent should print out the pid of each child after it finishes. The standard output of 'ls -al process should be piped to the input to the 'grep minishell.c process. Make sure you close the unnecessary open files for the three processes. The output should be the one line that includes the directory entry for minishell.c. You will need to call the source file minishell.c for this to work properly. Please follow the following instructions carefully before submitting your work: You need to create a Makefile to build your source code into an executable. The Makefile should also include a target 'clean' to clean up miscellaneous files (.o,, core, etc.). Before submission, make sure you clean up the directories so that no miscellaneous files are kept around in the submission. (Grade would be deducted if useless files are found in the homework directories.) The file to be submitted should be named as 'FirstnameLastnameL5.zip and submitted in the assignment dropbox in Canvas If the program does not compile and do something useful when it runs it will not earn any credit. 1.
