2.2 Crontab Format

Crontabs used by micrond are mostly compatible with Vixie crontabs. They are plain text, line-oriented files. When parsing a crontab, the leading and trailing whitespace on each line is ignored. Comments are introduced by a hash sign (#) appearing as the first non-whitespace character in a line. Comments and empty lines are ignored. Very long lines can be split across several physical lines using backslash as continuation character. Total length of a valid crontab line after removing continuation characters cannot exceed 1024 characters.

Each crontab line is either a cronjob definition or a variable setting.
