in thread custom name to the process

Well, you can check the value of $0 and do different things with it. But probably the best solution is to use different parameters to ps. For instance, ps -fe will give you the parameters passed to each instance, which is probably a pretty good way of distinguishing your processes.

    As has been hinted at, some OSes specifically disable showing of parameters, as showing those can prove to be security hole....e.g. you can see which config files are used by some programs OR even see userid/password passed to a program as parameters.
    symlinks are probably the best bet, as you can't reserve PID, for reasons of OS stability/security. You could easily though print the PID from the program when it starts each time, by printing the $$ variable.
    the hardest line to type correctly is: stty erase ^H
