Requirement: I have shell script for updating security patches on Linux servers which has to run on maintenance timings/windows.
What we have tried as suggested here:
We are trying to edit /etc/crontab file as below:
30 13 16 * * root [[ $(date "+%Y") == 2020 ]] && /path/to/shellscript
Issues: We are not able to execute above cron job:
o/p in logs:
CROND[24576]: (root) CMD ([[ $(date "+)
I am sure I am missing something in syntax of the cronjob but not sure what is that.
Please help me in resolving the issue.
