You may want to check out this thread I found at:

http://www.unix.com/shell-programming-scripting/27923-frustrating-disk-space-script.html

or use your favorite search engine to find a script. Hopefully other forum users will be able to provide you with some pointers as well.

I’m not very familiar with shell scripts myself. Hopefully other forum users will be able to provide you with some insight. You may also want to try posting your question on a forum like http://www.unix.com/shell-programming-scripting/ that is more geared towards scripting.

@jwala You can use the command df -k, but I think the command ‘df -hTa’ is better since it outputs it in a much easier to read format!

You could even script something to run in crontab every so often and then pipe it to email so you get a daily report. Something like this…

#!/bin/bash
df -hTa | mail -s subject diskuser@emailaddress.com

Could anyone help me out for this…..
if [ ${check} != "" -a ${check} !="0" ] ; then
this if loop shows too many arguments error

and the part of the code is :

if [ ${check} != "" -a ${check} != "0" ]; then
log_msg “printf $MSG_UPLOAD_PING_INVALID_STATUS ${check}“
while :
do
input
case $INPUT in
y* | Y*)
break 2
;;
n* | N*)
break
;;
*)
continue
;;
esac
done
else
break

guys, please help me ou am frustrated by this code

if loop shows en error named “[: too many arguments"
piece of code is here

if [ ${check} != "" -a ${check} != "0" ]; then
log_msg “printf $MSG_UPLOAD_PING_INVALID_STATUS ${check}“
while :
do
input
case $INPUT in
y* | Y*)
break 2
;;
n* | N*)
break
;;
*)
continue
;;
esac
done
else
break
fi

(“$MSG_UPLOAD_PING_INVALID_STATUS ${check}” – this will display their corresponding messages. No need to worry about the $ things)

@jwala: you need quotes around the ${check} variable substitution to handle the case where it has no value.
