The execution of the pipex program mimics the functionality as a shell command that looks like this:
< file1 cmd1 | cmd2 > file2To do this, the pipex program should be executed this way:
./pipex file1 cmd1 cmd2 file2file1 is the input filename
file2 is the output filename
cmd1 and cmd2 are shell commands with their parameters
I also made a tester for this project, make sure to check it out and test your own pipex!
