Write a program that takes a filename as a command$-$line argument and performs the

following steps:

$1.$ Open the file specified as the command$-$line argument.

$2.$ Read contents of the file one$-$line at a time.

$3.$ Use fork$-$exec to create a new process that executes the program specified in the

input file along with the arguments provided.

$4.$ The parent process will make note of the time the program was started $($you can

use a timer such as the time function defined in to capture the time before

the fork method is invoked, you can find out more about time function by

typing man time$).$

$5.$ Then the parent process will wait for the child process to complete and when the

child process terminates successfully, the parent process will capture the time the

child process completed $($you can again use a timer function to capture the time

when the wait function returns$).$

$6.$ Open a log file $($say$,$ output.log$)$ and write the command executed along with

arguments, start time of the process, and the end time of the process separated by

tabs$.$ Use ctime function to write the time in a human readable form.
