The aim of the project is to code the Pipex program.
./pipex file1 cmd1 cmd2 file2
File1 and file2 are file names, cmd1 and cmd2 are shell commands with their parameters.
The execution of the pipex program should do the same as the next shell command:
< file1 cmd1 | cmd2 > file2
./pipex infile ``ls -l'' ``wc -l'' outfile
Should be the same as “< infile ls -l | wc -l > outfile”.
./pipex infile ``grep a1'' ``wc -w'' outfile
Should be the same as “< infile grep a1 | wc -w > outfile”.
