TEXT: validate crontab
command
/cronvalid
description
Do very simple validation of given crontab text. [EXPERIMENTAL]

Very simple and rudimentary. Checks only for the most obvious error in the most basic crontab syntax.

EXAMPLES:
• valid: 00 12,20 * * 0,3,6 cmd
• not: 00 12,20 * 0,3,6 cmd
• not: 00 12,20 * * 0,3 6 cmd

Only checks that every non-comment non-blank lines begins with 5 sets of numbers or an asterisk. Also checks that the first character after the 5 sets is not a number or an asterisk. Numerical values are not validated. "Advanced" syntax is not supported.
