Shell Programming and Scripting

Hi Folks,

I have a log file that keeps the information pn the date and time a specific transaction is firedup. I found that the log file keeps growing and I intend to limit the entry to the log file to 30 days.

Log file name is transaction.log, here is the content:

120802_23:47:37 abbbbccccc
120802_23:52:23 accccddddd
120802_23:57:23 adddeeeee
120902_00:01:03 abbbbbccccc
120902_00:02:28 accccddddeee
120902_00:02:37 eeeeddddddbbb
120902_00:02:48 eeeddbbbb
120902_00:02:57 aaaaeee

The first column represent the execution date and time, while the right column indicate ths transaction name. Using the date, how can I limit the data in the transaction.log to 30 rolling days.


Thanks,

I would do something like:

Code:

cp transaction.log transaction.log$(date "+%Y%m%d")
> transaction.log
find . -name transaction.log\* -mtime +30 -exec rm {} \;

once a day via a cron job that runs during the last minute of the day.

Thanks Perderabo, I'll give that a trial.

You saying, you want to clear out the log file,after 30 days.

Well heres a perl script i wrote to clear out a log file.if ur anygood at perl ( unlike me ) you can adapt it or use cron to run it.

code below :

#util to clear log file
#version 1.0
#-colinok

#usr/bin/perl

#open file
open (LOG, "> ENTER PATH TO FILE HERE ")
$log = LOG;

#clear file
print clear $log;

#close file
close (LOG);


hope this helps
