shush

runs a command and optionally reports its output by mail

shush was written to be a generic wrapper around cron jobs so that it can be applied to any command without having to modify it or create a custom wrapper for it. In a sense, it solves a fairly simple problem, but it also brings some powerful features making it a useful tool beyond cron jobs. Feature highlights: * Multiple reports (for the output) may be defined * Decision to send a report (or not) is configurable based on: - Output content analysis (using regular expressions) - Command exit code - Size of output - Command execution duration * Support for plain text, enriched text and HTML report formatting. (The latter two allow rendering part of the output in bold.) * Various timeout actions such as notification and command termination * Locking support * Progress report logging via syslog * Automatic crontab file updating based on shush's configuration
