How is it possible under UNIX to restrain the number of digits of the PID number?
For instance, we have a product that generates a PID of 7 digits, and we would like to have only 6 digits maximum instead for the PID.
Thank you for your help.
This question does not make any sense. In every version of UNIX that I know of, PID's are in the range of 0 through 32000 and thus are restained to 5 digits. And introducing a further restraint to, say, a max of 9999 would require access to source code. It is certainly not tunable.
What version of UNIX are you using? What makes you think that you have 7 digit PID's?
I think that it's very unlikely indeed that you really have 7 digit PID's. But if you do, remember that no one is forcing you to display them in base 10. The largest 7 digit base 10 number is 9999999. In hexadecimal that's 98967F.
