Can I parse an active log file?

[goliath]

Hello,

I'm looking into how to parse an active log file. It does not seem to be locked open - but is appended to.

I would like to be able to parse the file as new lines are added.

I've read and parsed in-active files, that ends once it reaches the end tho.


Thanks!

This from the Perl Cookbook:

Read until the end of file. Sleep, clear the EOF flag, and read some more. Repeat until interrupted. To clear the EOF flag, either use seek:

for (;
{
while (<FH>) { ... }
sleep $SOMETIME;
seek (FH, 0, 1);
}

or the IO::Handle module's clearerr method:

use IO::Seekable;

for (;
{
while (<FH>) { ... }
sleep $SOMETIME;
FH->clearerr();
}
