Package: cron
Version: 3.0pl1-133
Severity: minor
Dear Maintainer,
I tried the following command line in the crontab:
* * * * * [ "$(date +%d)" -gt 10 ] && date >> /tmp/test.log
but when the condition occurred, no log file was generated.
I observed that the journal reported:
mar 15 11:05:01 UFFICIO CRON[29344]: (root) CMD ([29346] [ "$(date
+)
mar 15 11:05:01 UFFICIO CRON[29344]: (CRON) error (grandchild
#29346 failed with exit status 2)
so the problem was the percentage character that interrupted the command
and also generated an error
If I insert a backslash before:
* * * * * [ "$(date +\%d)" -gt 10 ] && date >> /tmp/test.log
it works well:
mar 15 11:08:01 UFFICIO CRON[30832]: (root) CMD ([30834] [
"$(date+%d)" -gt 10 ] && date >> /tmp/test.log)
Question: the percentage must be considered special character (I can't find
this in the documentation) or is it only a cron problem?
Thank you,
Antonio
