pipex

This project is about handling pipes.

Your program will be executed as follows:

./pipex file1 cmd1 cmd2 file2

It must take 4 arguments:

• file1 and file2 are file names.
• cmd1 and cmd2 are shell commands with their parameters.

It must behave exactly the same as the shell command below:

$> < file1 cmd1 | cmd2 > file2

Examples:

$> ./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
