Ssh Crontab Persist Tmp W Sh With Reboot And Hourly Execution If Missing

Reads existing crontab entries (crontab -l, ignoring errors). Checks whether an entry invoking /tmp/w.sh "astats" "netai" "kstats" "ssh 1 az" exists. If not present, prepends two entries: one @reboot execution of /tmp/w.sh with arguments, and one hourly (0 * * * *) execution from /tmp. Writes the updated combined entries back into crontab.
