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!

set_color

set_color(1)							       fish							      set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
