Full Discussion: Creating a shell script to check filesystem space
Operating Systems AIX Creating a shell script to check filesystem space Post 302075928 by backslash on Wednesday 7th of June 2006 03:21:44 PM

There's probably something wrong with setting the used space variable in from the df command.

It's good practise to quote your test parameters in double quotes so that if they are not set the test expression will not return with an error and treat the value as null.

I'm not near an AIX box at the moment but suggest you run the following from the command prompt to see what is returned:

df -k $mount_point | grep % | awk {'print $5'} | sed 's/%//g'

Ah just spotted what the problem might be. Try this (note the single quotes position)

df -k $mount_point | grep % | awk '{ print $5 }' | sed 's/%//g'

Hope that helps.

checksecurity

CHECKSECURITY(8)					      System Manager's Manual						  CHECKSECURITY(8)

NAME

       checksecurity - Run a collection of simple system checks

SYNOPSIS

       checksecurity

DESCRIPTION

       The checksecurity command runs a small collection of simple system checks which are designed to catch a few common security issues.  check-
       security is run by cron in a daily basis.

CONFIGURATION

       The checksecurity.conf file defines several configuration variables: MAILTO, CHECK_DISKFREE, CHECK_PASSWD and CHECK_SETUID LOGDIR.  Each is
       described below.

       The  checksecurity program works with a collection of plugins which are located in /usr/share/checksecurity and are configured individually
       by their own configuration file.

       CHECK_PASSWD If this is set to TRUE then the check-passwd script will be invoked.  This script is designed to report upon  system  accounts
       which  have  no passwords.  CHECK_DISKFREE If this is set to TRUE then the check-diskfree script will be invoked and will allow an alert to
       be sent if there is any mounted partition is running short on disk space.  CHECK_SETUID If this is set to TRUE then the check-setuid script
       will be invoked, this will compare the setuid binaries upon the system to those that existed previously and show the differences.

FILES

       /etc/checksecurity.conf
	      checksecurity configuration file
