Question Negative Numbers for input parameters.


I have a command that I need to supply a negative number as a parameter; how do I do this? I have tried giving it with double quotes, "", but no avail.

What error/errors are you getting when supply a negative number. I ran a simple script and here is what a have found.
$ cat ./
echo $old
$ ./ -5

Hi BubbaJoe,

Actually the flag is for a command that is in a shell script. It just tells me that the flag value is unrecognized and the command gets aborted.

The command is supposed to take both -ve and +ve values and works fine when the latter is supplied.

It will be easy if you give the actual command.
Let us say you want to give:
Code: -5

Then try:
Code: -- -5

This tells the shell that what follows is not an option but a param.
