Variable evaluation problem

[pgymjp]

Hey all,

I have the following code:

syntax="Usage: ${scriptName} [desiredMountPoint] [--noping]"
echo syntax;

I get: Usage: foo.sh [desiredMountPoint] 1

Where does the "1" come from and how is it being evaulated to it? "[-noping]" displays "[-noping]" just fine. Escaping out the square brackets and/or dashes no longer evaluates the "[--...]", but I have goofy looking output:

"\[\-\-noping\]"....obviously, I don't want that.

What I want:
syntax="Usage: ${scriptName} [desiredMountPoint] [--noping]"
echo syntax;

Usage: foo.sh [desiredMountPoint] [--noping]

Thanks,
Jeff

Seems like it has to be coming from the mount command returning a one on a failure to mount.

There's no mounting going on at this point of the script. I just wanted to echo out the syntax of the script for anyone who called it with a "-?" or "--help" argument.

Anyway, I figured it out:
echo $syntax gave me the funky variable eval to "1".
echo "${syntax}" stopped the funky var eval. Everything looks good now.
