Pipex is a project that focuses on understanding how UNIX mechanisms work.
The project involves handling pipes in a manner that mimics the behavior of a shell.
The mandatory part of the project requires handling one pipe.
The program should behave in the same way as the shell command shown below:
$> < file1 cmd1 | cmd2 > file2
$> ./pipex infile "ls -l" "wc -l" outfile
should behave like:
< infile ls -l | wc -l > outfile
$> ./pipex infile "grep a1" "wc -w" outfile
should behave like:
< infile grep a1 | wc -w > outfile
pipex.c : Generating child processes and creates files with error handling.
single_quotations.c : Combining strings into a string surrounded by single quotation marks.
For example, it can handle the following command:
$> ./pipex infile "grep 'Have a nice day.'" "cat" outfile
command.c : Getting default shell commands directories through an environment pointer(char *envp[]) and check if a command is executable or not.
children.c : Redirecting STDIN and STDOUT to infile and outfile. It also executes commands if they are executable.
make
$> ./pipex infile 'cmd1' 'cmd2' outfile
