[C Language] Write a C code to produce a Bash script to replace a routine job, 

Result :

Use a C code to produce the command like below.

 

./z_First_Step ./IN/happy1.htm

./z_Second_Step Html2.txt TestScript

./z_Third_Step Html2.txt ./OUT/happy1.sh



./z_First_Step ./IN/happy2.htm

./z_Second_Step Html2.txt TestScript

./z_Third_Step Html2.txt ./OUT/happy2.sh

Write a C code.

Execute bin file and put one parameter into this C code. Then produce the Result.

Create execute bin file to create sh

./RunSh happy1

./RunSh happy2
