One thing you might try is using the double parens math workings of bash. Quite cool and is readable, and it avoids your shell expansion problem. Secondarily, a "here" document with the "dc" program is how I used to do it. e.g.:

dc <<EOF
2 20 * p
EOF
will produce 40 as output

Using the double-parens syntax of bash, one can do this:

$i=0
((i=2*20))
echo $i <-- produces 40

Kinda cool, huh?

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. AUTHOR
tntnet was written by Tommi Makitalo <tommi@tntnet.org>. This manual page was written by Kari Pahula <kaol@debian.org>, for the Debian project (but may be used by others). SEE ALSO
