Hi Monks

Just want to what is the best way to read the rotated file i am developing a log monitoring solution for Solaris Syslog where i am reading the /var/adm/messages file. At the time of rotation the Archived file messages.1 will have some latest errors how to handle this situation. The current logic which i am trying to concatenate the two files messages and messages.1 and sending the errors. Is there any best possible way to handle this log rotation other than concatenating the files. which is a very slow process

    You could use File::ReadBackwards to read messages.1 until you reach the point where your previous scan ended. That way you only need to read the lines you need rather than the whole file.

      Thanks for your help will the File::ReadBackwards takes the cursor position since i am using tell function to store the current position of the file

    Please note that the section "Perl Monks Discussion" is " only for discussing issues pertaining to the PerlMonks web site."

    Please use the section Seekers of Perl Wisdom for "question on how to do something in Perl, or you need a Perl solution to an actual real-life problem, or you're unsure why something you've tried just isn't working..."

    I have moved this to SoPW.

    Second post today!!
