xargs.py

Python module to implement xargs-like (but better) functionality.

The POSIX utility xargs is fantastic.

However, we can do better, particularly if we are using a programming language that offers more than your average shell... like python.

The included python file implements a library. This library offers the following features over xargs:

• Possible to implement a pipeline.
• You don't need to worry about terminating anything (because it's Python; Python knows where its strings end).
• You don't need any special data structures; just lists of lists of lists of strings.

Is it perfect? Nope.

Is it pretty darn good? I think so, yes.

Example usage:

xargs([
    [
        ['infile1',],                ['infile2',],
    ],
    [
        ['grep','CCACTACTT',],      ['grep','CCACTACTT',],
    ],
    [
        ['fold','-w', '10',],       ['fold','-w', '10',], 
    ],
    [
        ['outfile1',],              ['outfile2',],
    ],
], 1)
