nrbt is a tool to wrap commands and scripts launched via cron. It goals is to provide an output only if:
- stderr was not empty
- the process exit with a code other than 0 (it is possible to add "valid" exit
codes using the
-e
option).
If such cases happen, a simple report will be printed on stdout so cron can
send it at the address configured in the MAILTO
variable.
This report can also be written to a file (it will be written even if the execution ended well).
% nrbt myscript.sh -o /var/log/myscript.log
