Instructions

Clone this repository in your local computer:

$> git clone https://github.com/lmoraesdev/pipex.git path/to/pipex

In your local repository, run make

$> make 

make suports 6 flags:

• make all or simply make compiles pipex in its mandatory format
• make bonus compiles pipex in its bonus format
• make clean deletes the .o files generated during compilation
• make fclean deletes the .o and the pipex file generated
• make re executes fclean and all in sequence, recompiling the program
• make rebonus executes fclean and bonus in sequence, recompiling the program with the bonus functions

To run pipex, type:

./pipex files/<choose-input-file> cmd1 cmd2 files/<choose-output-file>
# works like: 
< files/<choose-input-file> cmd1 | cmd2 > files/<choose-output-file>

For bonus' here_doc option, type:

./pipex here_doc LIMITER cmd1 cmd2 files/<choose-output-file>
# works like: 
cmd1 << LIMITER | cmd2 >> files/<choose-output-file>

./pipex also works with multiple pipes.
