Disk Usage Report Script

your_shadow03 · 02-21-2014, 09:07 PM

I have a Solaris script for showing disk usage as shown below:

Code:

home/l> space
                         SPACE OF IMPORTANT FILE SYSTEMS
------------------------------------------------------------------------

function disp(color_code,v1,v2,v3,v4,v5){
printf "\033[1;"color_code"m%-10s\t%10s\t%10s\t%10s\t%6s\033[m\n",v1,v2,v3,v4,v5
}

END{print "-------------------------------------------------------------------------\nColor Significance for USED spaces:   \033[1;31mgt-80 % \033[m \033[1;33mlt-80 % & gt-40 %\033[m \033[1;32m lt-40 %\033[m"}'

Its not running on Linux as it doesnt detect df -gt command. Any idea how to get it run under Linux?
While I ran the script:

Code:

./space
df: invalid option -- 'g'
Try `df --help' for more information.

The script is not displaying correctly.

Code:

grep 'Filesystem\|\/tmp\|\/home\|\/var/lib/psa\|\/opt\|\/var/log\|\/var'

You have changed the list of directories from those in your original post, so the grep pattern needs adjustment.
Are you really mounting volumes on /var/lib/psa and /var/log? If so, then properly escape the forward slashes in the grep pattern.

All I want is to monitor /var/lib/psa/dumps, /home, /usr and /tmp directories.
The df shows below:

Code:

[root@u16868920 psa]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1              12G  2.5G  9.6G  21% /
/dev/mapper/vg00-usr  4.0G  2.1G  1.7G  57% /usr
/dev/mapper/vg00-var  103G  6.7G   91G   7% /var
/dev/mapper/vg00-home
                      4.0G  137M  3.7G   4% /home
none                   16G  1.6M   16G   1% /tmp

That shows why the script is failing. The output from /dev/mapper/vg00-home has been split across two lines.
As your script does not use the $1 field, you could modify the script to include the '--output' option to df and modify the field positions used by awk accordingly.
