ex - 80% , 85% ,90%,95%,100% we should get an email

Code:

#!/bin/bash
MAILTO="monitoringbox@abc.com"
Thershold=80
output=""
temp=/tmp/diskvalue
HOSTNAME=`hostname`
rm -f $temp
output=`df -H | *grep -vE '^Filesystem|tmpfs|cdrom|' awk '{ print $5 " " $6 }'`
usep=$(echo $output | awk '{ print $1}' | cut -d'%' -f1 *)
partition=$(echo $output | awk '{ print $2 }' )

if [ $usep -gt hershold ]; then
echo "Running out of space \"$partition ($usep%)\" on $(hostname) as on $(date)" >> $temp

if [ -e $temp
then
mail -s "Disk spe on $HOSTNAME $usep *`date` " $MAILTO < $temp

I tried couple of options using while loop but could not get right one
Any help is highly Appreciated

Hi anil529,
Ignoring everything that you and drysdalk have been discussing, someone should also note that the script that you have shown us above can't possibly be doing anything useful. Everything marked in red above will cause your script to fail in various ways (mostly syntax error for ifs with not matching fis, [ with no matching ], hershold instead of $Thershold (and why Thershold instead of Threshold?), cut being used to read data from a pipeline when given file operands, and an empty alternative in an ERE. (And, I make no claim that this is a complete list of the problems in your current script!) If you are trying to modify an existing working script; PLEASE show us the actual working script!

alert

alert(3alleg4)                                                    Allegro manual                                                    alert(3alleg4)

NAME

       alert - Displays a popup alert box. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       int alert(const char *s1, *s2, *s3, const char *b1, *b2, int c1, c2);

DESCRIPTION

       Displays  a  popup  alert  box,  containing  three lines of text (s1-s3), and with either one or two buttons. The text for these buttons is
       passed in `b1' and `b2' (`b2' may be NULL), and the keyboard shortcuts in `c1' and `c2' as ASCII value. Example:

          if (!exists(CONFIG_FILE))
             alert(CONFIG_FILE, "not found.", "Using defaults.",
                   "&Continue", NULL, 'c', 0);

RETURN VALUE

       Returns 1 or 2 depending on which button was clicked. If the alert is dismissed by pressing ESC when ESC is not one of the keyboard  short-
       cuts, it treats it as a click on the second button (this is consistent with the common "Ok", "Cancel" alert).
