I'm fascinated by the intersection of argv[0], and the execve behavior of replacing the calling program with the called one.

Aside from that, I quite like argv[0], for a much more limited set of reasons than considered in this interesting and comprehensive article. I like the ability to "retitle" a process to put a useful, descriptive, or branded name in there to be seen by ps, et al.

NodeJS also exposes this feature, but not quite as you might expect. Whereas in C, setting argv[0] from within the program's execution context will alter what is observed by ps, in NodeJS process.argv is just a descriptive getter. Setting its slots has no effect outside of its context.

But this is where process.title steps in. Setting process.title allows you to (in an OS-dependent way) change the name reported in ps and similar tools.

Please don't kill argv[0], its lease hath all too short a date
