Full Discussion: Script for deleting files and directories when the file system reaches the threshold
Top Forums Shell Programming and Scripting Script for deleting files and directories when the file system reaches the threshold Post 302589525 by mirni on Thursday 12th of January 2012 03:47:43 AM

This should do the trick:

Code:
#!/bin/bash
use=`df | grep /sybase | awk '{print $(NF-1)}'`   #get the percentage use 
use=${use%*%}  #get rid of the trailing '%'
if [ $use -gt 94 ] ; then
    rm -r /sybase/logs/*
fi

This script should be run by cron as often, as you think is necessary (every hour, day?). If you want it to run every hour, just copy it into /etc/cron.hourly, if that exists on your system. If not, then make an entry in the crontab. Make sure the script is executable.

rt-email-dashboards(8)					     Request Tracker Reference					    rt-email-dashboards(8)

NAME

       rt-email-dashboards - Send email dashboards

SYNOPSIS

	   rt-email-dashboards [options]

DESCRIPTION

       This tool will send users email based on how they have subscribed to dashboards. A dashboard is a set of saved searches, the subscription
       controls how often that dashboard is sent and how it's displayed.

       Each subscription has an hour, and possibly day of week or day of month. These are taken to be in the user's timezone if available, UTC
       otherwise.

SETUP

       You'll need to have cron run this script every hour. Here's an example crontab entry to do this.

	   0 * * * * /usr/bin/perl /opt/rt4/local/sbin/rt-email-dashboards

       This will run the script every hour on the hour. This may need some further tweaking to be run as the correct user.

OPTIONS

       This tool supports a few options. Most are for debugging.

       -h
       --help  Display this documentation

       --dryrun
	       Figure out which dashboards would be sent, but don't actually generate or email any of them

       --time SECONDS
	       Instead of using the current time to figure out which dashboards should be sent, use SECONDS (usually since midnight Jan 1st, 1970,
	       so 1192216018 would be Oct 12 19:06:58 GMT 2007).

       --epoch SECONDS
	       Back-compat for --time SECONDS.

       --all   Ignore subscription frequency when considering each dashboard (should only be used with --dryrun for testing and debugging)
