I've been trying to get the syntax right so I can echo a $var and then text around it or after it. It either wont display text or $var or one overwrites the other at the beginning of the line. Trying to do something like this.
Its an older version of bash on Solaris 10.
Ultimately what I'm trying to do is add two decimal numbers. I've tried bc and dc but I cant get them add with vars instead of numbers.
I have a ksh script that is a login menu for my end users. I would like to have one line of the welcome message flash when there is a system notice about an impending outage.

Hi Experts
I need your help to optimize my script to execute better as I have nearly 1M records & the script is taking close to 40 minutes to execute, so would need support on a faster alternative.

escape
escape(1) Mail Avenger 0.8.3 escape(1)NAME
escape - escape shell special characters in a string
SYNOPSIS
escape string
DESCRIPTION
escape prepends a "" character to all shell special characters in string, making it safe to compose a shell command with the result.
EXAMPLES
The following is a contrived example showing how one can unintentionally end up executing the contents of a string:
$ var='; echo gotcha!'
$ eval echo hi $var
hi
gotcha!
$
Using escape, one can avoid executing the contents of $var:
$ eval echo hi `escape "$var"`
hi ; echo gotcha!
$
A less contrived example is passing arguments to Mail Avenger bodytest commands containing possibly unsafe environment variables. For
example, you might write a hypothetical reject_bcc script to reject mail not explicitly addressed to the recipient:
#!/bin/sh
formail -x to -x cc -x resent-to -x resent-cc
| fgrep "$1" > /dev/null
&& exit 0
echo "<$1>.. address does not accept blind carbon copies"
exit 100
To invoke this script, passing it the recipient address as an argument, you would need to put the following in your Mail Avenger rcpt
script:
bodytest reject_bcc `escape "$RECIPIENT"`

BUGS
escape is designed for the Bourne shell, which is what Mail Avenger scripts use. escape might or might not work with other shells.
