Hi all, im new to the forums and i hope im not asking a heavily posted Q but here goes.
I use the following script to do a simple calculation, the problem is, the data i receive is in the form of numbers with commas i.e.
1,000,000
This code below wont recognise the commas so i have to remove them. If anyone has a simple solution or even point me in the right direction that would be grand. It's a little hard to search for an error with such a common word like "comma".
Code:
#! /bin/bash
echo "What is the Lowest Threshold?" ;
read LOW ;
echo "What is the highest Threshold?";
read HIGH ;
echo "How much data have you received?";
read DATA ;
THRESHOLD=`expr $HIGH - $LOW` ;
if [ "$DATA" -gt "$HIGH" ] ; then
DIFF=`expr $DATA - $HIGH` ;
DATA=`echo "scale=2; ( $DIFF / $THRESHOLD ) * 100" | bc` ;
echo "$DATA percent above the threshold.";
echo "Press 'enter' to continue" ;
read cont ;
elif [ "$DATA" -lt "$LOW" ] ; then
DIFF=`expr $LOW - $DATA` ;
DATA=`echo "scale=2; ( $DIFF / $THRESHOLD ) * 100" | bc` ;
echo "$DATA percent below the threshold.";
echo "Press 'enter' to continue" ;
read cont ;
else
echo "This data is within the threshold limits.";
echo "Press 'enter' to continue";
read cont ;
fi;

service(8) System Manager's Manual service(8)NAME
service - run a System V init script
SYNOPSIS
service SCRIPT COMMAND [OPTIONS]
service --status-all
service --help | -h | --version
DESCRIPTION
service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working
directory set to /.
The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the
invoked script, service passes COMMAND and OPTIONS it to the init script unmodified. All scripts should support at least the start and
stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start
command.
service --status-all runs all init scripts, in alphabetical order, with the status command.
EXIT CODES
service calls the init script and returns the status returned by it.
FILES
/etc/init.d
The directory containing System V init scripts.
ENVIRONMENT
LANG, TERM
The only environment variables passed to the init scripts.
SEE ALSO
/etc/init.d/skeleton,
update-rc.d(8),
init(8),
invoke-rc.d(8).
