Need help with arithmetic expression using variables
Hi,
I am trying to do a percentage calculation in a Bourne shell script. The following works fine, but when I try to subsitute the values 153824 and 246000 for variables (e.g. used and limit), I get errors.
calc()
{
awk 'BEGIN {OFMT="%f"; print '"$*"'; exit}'
}
calc '(153824 / 246000) * 100'
Can some one please help me with whatever it is that I am missing?
Thanks!

tntnet
tntnet(8) Tntnet users guide tntnet(8)
NAME
tntnet - web application server for c++
SYNOPSIS
tntnet [-c file] [--logall]
tntnet -C [-q query-string] [componentId ...]
DESCRIPTION
This manual page documents briefly the tntnet command.
tntnet is a web server that can generate dynamic content via precompiled C++ modules.
OPTIONS
A summary of options is included below.
-c file
Use file as the configuration file. If the -c is omitted, the first nonoption argument is used as the config file.
--logall
Initialize logging earlier. Normally logging is initialized after starting the listeners and changing user so that logfiles are cre-
ated with the right owner. For debugging reasons this option forces to do that earlier.
-C Call components and print the result to stdout instead of starting tntnet as a webserver
-q query-string
In -C mode pass this query string to the component. The option may be repeated multiple times to pass name-value-pairs easily.
EXAMPLE
tntnet -C -q arg1=35 -q arg2=7 -q op=/ calc@calc
calls the component calc@calc with query parameters and prints the result to stdout.
FILES
/etc/tntnet/tntnet.conf The default configuration file.
ENVIRONMENT
TNTNET_CONF
This is checked for the configuration file name if it is not specified on the command line.
