Do One Thing

In the spirit of UNIX, getargv does exactly one thing. It prints a PID's arguments. Therefore there isn't any need for a complex interface with many options. Anything that getargv doesn't do can be better achieved by piping its output into another tool.

The one allowance for surfeit is the redundant -? flag, which exists purely as aesthetic indulgence.

The options

-v

Print getargv's version number

-0

Print arguments ␀ separated (machine readable), default is space separated (human readable)

-s #

-?
