Title Body

My scripts cdist-deploy-to and cdist-mass-deploy (from cdist configuration management) run interactively (i.e. are called by a user). These scripts call a lot of scripts, which again call some scripts: cdist-mass-deploy ... cdist-deploy-to ... cdist-explorer-run-global ... cdist-dir .... What I want is to exit / kill all scripts, as soon as cdist-mass-deploy is either stopped by control C (SIGINT) or killed with SIGTERM. cdist-deploy-to can also be called interactively and should exhibit the same behaviour. Using ps -ef... and co variants to find out all processes with the ppid looks like it could be quite unportable. Using $! does not work as in the deeper levels the children are no background processes. I tried using the following code: __cdist_kill_on_interrupt() { __cdist_tmp_removal kill 0 exit 1 } trap __cdist_kill_on_interrupt INT TERM But this leads to ugly Terminated messages as well as to a segfault in the shells (dash, bash, zsh) and seems not to stop everything instantly anyway: # cdist-mass-deploy -p ikq04.ethz.ch ikq05.ethz.ch core: Waiting for cdist-deploy-to jobs to finish ^CTerminated Terminated Terminated Terminated Segmentation fault So the question is, how to cleanly exit including all (sub-)children in a portable manner (bourne shell, no csh support needed)?
