the wikipedia page sigchld says: the sigchld signal sent parent of child process when exits, is interrupted , or resumes after being interrupted. does mean when parent process sends signal (such sigterm ) child process, in turn receive sigchld child? or misinterpret interrupt (i assume mean any signal received ), in case, signals concerned? a sigchld delivered parent in these cases: the child process exits. the child process stopped sigstop, sigtstp, sigttin or sigttou signal the child process resumed sigcont signal i presume sigstop/sigcont wikipedia means "interrupted". the default handler sigterm terminate process. if parent sends sigterm child process terminates child, yes - parent receive sigchld. if child installs signal handler not terminate it, there no sigchld signal delivered parent.
