Pipex

Recoding UNIX pipes behavior in C

The goal of pipex is to execute a series of commands provided as arguments and redirect the output of one command as input to the next command, similar to the behavior of the pipe operator in a shell. It allows for the sequential execution of commands, with the output of one command serving as the input for the next.

The pipex utility uses file redirection and process execution to achieve this behavior. It creates pipes to establish communication channels between the commands, redirects standard input and output to files, and uses the fork and exec functions to execute the commands as child processes.

Compiling

Mandatory

After running make all you will have to execute the program like so:

./pipex file1 cmd1 cmd2 file2

It should behave similarly as:

< file1 cmd1 | cmd2 > file2

Bonus

After running make bonus you will have to execute the program like so:

./pipex file1 cmd1 cmd2 cmd3 ... cmdn file2

It should behave similarly as:

< file1 cmd1 | cmd2 | cmd3 ... | cmdn > file2

OR like so:

./pipex here_doc LIMITER cmd cmd1 file

It should behave similarly as:

cmd << LIMITER | cmd1 >> file
