Listing cron jobs or log files within a specific time frame is quite hard especially if the log or logs are quite a big file.
But of course, doing the lazy way but a smarter way is always a good option.
Use SED or stream editor.
In Centos the log is in: /var/log/cron
/var/log - path for the file
cron - is the file that keeps the record for cron jobs, there is no filename extension
To check the logs within the 24 hours time, sed can do it easily and quickly.
Here's one line, time saver command to check the cron log file:
sed -n '/Mar 10 00:00:01/ , /Mar 11 00:01:01/p' /var/log/cron
To redirect the output to a file:
sed -n '/Apr 10 00:00:01/ , /Apr 11 00:01:01/p' /var/log/cron > cron24_hours.record.log
You can replace /var/log/cron with any other files as long as it follows the time format of Month, Day of the month and the time in HR:MM:SS format.
