Re: How to read from rotated log file?

[JavaFan]

I assume your system numbers log files, and that compressed log files end in .gz.

Let's assume your base file is called "my-app". Then it's time to use magic open! Untested:

my @files = </var/log/my-app*>;
/\.gz/ and $_ = "zcat $_ |" for @files;
local @ARGV = @files;
while (<>) {
    ... do something with record ...
}

This will read uncompressed files in the usual way, and read from a pipe (with zcat on the other end) for compressed files.
