Please post the exact and precise (to the last decimal place) range of the parameter or parameters you are trying to validate. The Shell normally deals with integers ... but there is always another way. I think that my post is the only one which works so far. The awk and perl programmers have kept quiet so far ... perhaps because we are all having difficulty visualising your computer.
Do you have any computer programming languages available on your computer - expecially any in which you have expertise?
Hey Methyl,
That was so nice of you in taking time to write a detailed message.
It is an already being used shell script (program.sh) on my GNU Linux server.
The program was developed by another person that accepted only whole numbers(1,2, 3, 4, .....) but not decimals.
I just added the " | bc " to my program and it works now.
Earlier before, the first line in my code used to be #!/bin/sh and it gave me some errors saying cat and sed commands couldn't be found.
But, now I changed it to #!/bin/bash and the program is running without my earlier "arithmetic errors". I will let this post know how my output or errors are headed to.
Hello
You know how to ask for the existence of one parameter and depending about it then do something, example:
Original script:
###################
USER=$1
PASS=$2
program1 $USER $PASS
###################
Desired shell
###################
USER=$1
PASS=$2
ARCH=$3
if
then

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"`

The Mail Avenger home page: <http://www.mailavenger.org/>.
BUGS
escape is designed for the Bourne shell, which is what Mail Avenger scripts use. escape might or might not work with other shells.
