Originally posted by LivinFree If you just want to clear out that one periodically, it may just be easier to whip up a little script that cp's it to another file (in case you want to review it later), compresses the archive, and truncates that file.
Here is a little Perl script that I cooked up for automagically rotating logs of an application that sends the data to STDOUT and redirected to file.
Seems that in the above situation that you can't just cp the file as the inode pointer will still point at the new filename and keep on adding data (I simulated this on my FreeBSD system for a thread on another forum).
Code:
#!/usr/bin/perl
# Real cheezy attempt at piping STDOUT into a perl routine to automagically
# rotate logs. Idea inspired by cRock.
# Auswipe sez "Hey, no guarantees!"
my $lineCounter = 0;
my $logCount = 1;
#open(LOGFILE, ">app.log.$logCount");
while (true) {
if (($lineCounter > 1000) || ($lineCounter == 0)) {
close(LOGFILE);
open(LOGFILE, ">app.log.$logCount");
$logCount++;
$lineCounter = 1;
# print STDERR "Rolled log to app.log.$logCount\n";
};
$logEntry = <STDIN>;
$lineCounter++;
print LOGFILE "$logEntry";
#print STDERR "Made log entry.\n";
};
Usage:
Code:
./someapp | ./perl_buffer
Hmmm. After looking at my code I realize that I could just keep on incrementing $lineCounter and just use modular arithmatic to set the point to rotate the log. That'll teach me.

Hi,
Last day, In one of our unix boxes there was an issue wherein few of the directory structures were missing / got deleted.
Is there any way by which we can find how it happened, I mean by going through syslog / which user had run what command?
Thanks for your help (3 Replies)
