The cron manpage is correct (no mention of using \ for anything but an escape character). The https://docs.freebsd.org/doc/13.0-RELEASE/usr/local/share/doc/freebsd/en_US.ISO8859-1/books/handbook/configtuning-cron.html <https://docs.freebsd.org/doc/13.0-RELEASE/usr/local/share/doc/freebsd/en_US.ISO8859-1/books/handbook/configtuning-cron.html>; page is incorrect. I’ve also checked the source at https://github.com/freebsd/freebsd-src/blob/373ffc62c158e52cde86a5b934ab4a51307f9f2e/usr.sbin/cron/lib/entry.c There is no code to merge lines ending with a \ into a single command. And I agree, for a large number of sequential commands, a shell is going to superior is every way. You could also add error recovery, etc. > Askhome | help
