Shalom,

cd /var/log

ls -lrt

That will reverse order display by date so you know what has been updated recently.

/var/log/messages is in order and I would suggest using the tail command.

I personally would just use vi and ctrl-g to get to the bottom of the file.

Would some form of the below be what you are looking for ?

# find /var/log/ -name "messag*" -exec grep -B3 -A3 -i "cron" {} \;

Enjoy life.

You will have to use grep, but without some scripting, hard to find specific ten days.

For example:

grep Mar messages | grep

But, remember that cron handles it's specific log file /var/log/cron.

This would return the syslog entries of the last 10 days:

for ((i=0;i<11;i++)); do grep "$(date --date="$i days ago" +%b' '%d)" /var/log/syslog; done


take care, if the date is below 10 maybe there's a space missing in the grep. Try around a bit, that example should be a nice base for improvements :)

yes you are right, I just did a small change and now its working even when the date is below 10

for ((i=0;i<11;i++)); do grep "$(date --date="$i days ago" +%b' '%e)" /var/log/messages |grep "cron"; done

i.e instead of '%d' I use '%e' with 'date', and its working with the date below 10. ;)

Thanks
