Struct ProcessSession

pub struct ProcessSession;

Available on Unix and crate feature process-session and crate feature std only.

Wrapper which creates a new session and group for the Command.

This wrapper is only available on Unix.

It creates a new session and new process group and sets the Command as its leader. See setsid(2).

You may find that some programs behave differently or better when running in a session rather than a process group, or vice versa.

This wrapper uses the same child wrapper as ProcessGroup and does the same setup (plus the session setup); using both together is unnecessary and may misbehave.
