emanuele6 1658629885 learn `kill -9 -- "$pid"' or `kill -USR1 -- "$pid"' will not work in dash (even though they should according to POSIX): when the first argument of kill(1) starts with a "-" followed by a valid signame or signum, dash will not handle options, and will just use the rest of the arguments as jobspecs (including `--' which will cause an error). Instead of `kill -USR1 --', you can use `kill -s

Use `kill -s USR1 --' instead. If you need to use a signum, the only solution is to remove --.
