You can try this :

find /path_to_files -iname "*.file_extension" -mtime -period_of_time -print

where is :
iname , i means , not to pay attention on big/small letters in name

-period_of_time --period of time you are want to search

So if you want to look for txt files changed in last 15 days and in /home directory command would be

find /home -iname "*.txt" -mtime -15 -print

Hope this helps

Usually, on Linux one has logrotate working.

If nothing else is defined in
/etc/logrotate.d/syslog
then the global rotation scheme as defined in
/etc/logrotate.conf holds which is "daily".

Then check your crontab when the daily jobs are executed.

# grep daily /etc/crontab
02 4 * * * root run-parts /etc/cron.daily
# ls -l /etc/cron.daily/logrotate
-rwxr-xr-x 1 root root 180 Jul 13 2005 /etc/cron.daily/logrotate

So, on my sample box rotation starts daily at 04:02

Now, depending how many rotation cycles or generations are defined in either
/etc/logrotate.d/syslog or
/etc/logrotate.conf
that many days back of syslog (messages) you will have before older rolled files will be overwritten with newer ones.
For older logs you would have to restore them from your backups.
