PIPEX

This is a project handling shell pipes.

MANDATORY PART

The mandatory version works with only one pipe.

You should run the program like this:

./pipex infile cmd1 cmd2 outfile

The output is expected to behave the same way as the following command:

< infile cmd1 | cmd2 > outfile

The infile must exist.

cmd1 and cmd2 are shell commands such as grep, ls, cat or any other.

The outfile will be created if it does not exist yet.

BONUS PART

The bonus part works with multiple pipes like this: ./pipex_bonus infile cmd1 ... cmdn outfile

The bonus part also handle heredocs. This means that you provide the input in the terminal instead of giving an input file.

This is how you can use my program with here doc:

./pipex_bonus here_doc LIMITER cmd1 ... cmdn outfile

LIMITER is the word after which the terminal stops asking for input.

The output is supposed to behave the same as:

cmd1 << LIMITER | cmd2 | ... | cmdn >> outfile
