[Semi-OT] Process *name* a valid concept in Unix/Linux?

[Ron Johnson <ron.l.johnson@cox.net>]

Hi,

I know that you can see a pid and it's complete command line, but is 
there the concept of "name"?

For example, in OpenVMS, you can do:
  $ SET PROCESS/NAME=SOMEUNIQUENAME

Then in SHOW SYSTEM (similar to "ps aux") you'll see a line with a 
pid and the text SOMEUNIQUENAME.  Also, no other process can have 
the same name, thus performing a similar function as lock files.

Or, since fork() is so integral to Unix and processes keep flitting 
in an out of existence, is "name" not a relevant concept?

Thanks
