You're doing nothing wrong - apparently non-interactive INT handlers have never worked in fish, see: https://github.com/fish-shell/fish-shell/issues/6649 In an interactive session, it kind of works function on_SIGINT --on-signal SIGINT echo "Got SIGINT!" end while true; echo press ctrl-c; end However, when an external program is running, the handlers don't seem to work. When replacing the while loop with "sleep 10", the signal handler is not run on ^C. Of course we want to improve non-interactive fish but for now I'd stick with a POSIX shell for this task. > My actual use-case is a script that will eventually call openconnect to > establish a VPN connection to my work network.

Integrating the scripts in your system's service manager seems like the proper solution. By specifying the mounts' dependency on openconnect this could probably be automated nicely. > > I'm running fish 3.1.2. > > Thanks for any pointers, > Tassilo > > > > _______________________________________________ > Fish-users mailing list > Fish-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/fish-users _______________________________________________ Fish-users mailing list Fish-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/fish-users
