disown cannot find ones self, or a child

I'm in a nested shell trying to use disown to re-root myself as well as a child. Looks like this:

Code:

# echo $$
1234

# disown 1234
disown: job not found: 1234

# disown $$
disown: job not found: 1234

# pgrep mychild
2222

# disown 2222
disown: job not found: 2222

This is in zsh. The goal is to have process 1 (the root of all processes) to become the parent.

Can't you simply start the jobs with a trailing "&"?

That would only background the new job. The new job would still be a child of the current shell, which means when the current shell terminates, the child does too.

The disown built-in accepts a jobspec as argument, not a PID. If you have a running job whos job ID is 1, the related disown syntax is

Code:

disown %1

where %1 is the jobspec. If you want to disown all the jobs from the current shell use

Code:

disown -a
