pipex is a 42 school project aimed to better understand shell redirection and pipes, by handling them in C.
This pipex program takes an input file, performs a command on it, pipes the result to another command which then writes its result to an output file. The result is virtually identical to this kind of shell command:
$ < input_file command1 | command2 > output file
Waiting for evals
To compile, use make, make all or make bonus.
Pipex can handle 2 or more commands. To execute:
$ ./pipex input_file command1 command2 ... commandn output_file
The output will be written to the specified output file. If the output file exists, it will be overwritten. This replicates the shell command:
$ < input_file command1 | command2 | ... | commandn > output_file
Each command can be given arguments and options if surrounded by quotation marks. For example:
$ ./pipex example.txt "cat" "grep x" "sed s/l/.../g" outfile.txt
You can also run pipex with a heredoc, like this:
$ ./pipex here_doc LIMITER command1 command2 ... commandn output_file
You will then be asked to input text which will be used as input for the commands. In this case, the specified output file will not be overwritten but appended, which replicates the behavior of the shell command:
$ << LIMITER command1 | command2 | ... | commandn >> output_file
