I'm firmly in that camp but I also always add `set -eux`, which makes it so much better at debugging as that gives you individual commands it runs before the output of them.
- figmert 2y agoTo be clear, the difference is something along this line: $ bash -ec 'echo hello && ls -la /tmp/ | grep systemd && false && echo testing' hello drwx------. 3 root root 60 Mar 29 18:33 systemd-private-bluetooth.service-yuSMVM drwx------. 3 root root 60 Mar 29 18:33 systemd-private-upower.service-YhHHP2 versus $ bash -euxc 'echo hello; ls -la /tmp/ | grep systemd; false; echo testing' + echo hello hello + ls -la /tmp/ + grep systemd drwx------. 3 root root 60 Mar 29 18:33 systemd-private-bluetooth.service-yuSMVM drwx------. 3 root root 60 Mar 29 18:33 systemd-private-upower.service-YhHHP2 + false Docker also supports the `SHELL` syntax now, which is even better, because you can set it once at the top of the Dockerfile without having to do the whole `set -eux` on every line.
