A more flexible perl solution, in case you have multiple mounts, in multiple locations. Also remote friendly

[code]
#!/usr/bin/perl

$command=$ARGV[0];
$name=$ARGV[1];


### Add your disk image name, and location here
%directories=("all","~/Desktop/all.dmg","none","~/Desktop/none.dmg");

if($command eq "mount")
{ system "hdiutil mount $directories{$name}"; }
elsif($command eq "unmount")
{
$mount_data = `mount`;
($dev)=($mount_data=~/(\/dev\/disk\d{1,2}).*?\/Volumes\/$name/);
system "hdiutil detach $dev";
}
else
{ print "sorry, must select mount or unmount";}
[/code]

Save as diskmnt.pl, make it executible by running chmod a+x diskmnt.pl, then dump it into /usr/local/bin
Works great for me, and is a bit more compact and easier for a command line guy like me to understand.

Any thoughts suggestions, let me know

Re: rattler14's script -

Handy, thanks. However, a few comments/questions:
1) When I tried to put the file in /usr/local/bin/ is gave me a permissions error and I had to login as root to place it. Is that normal?

2) Being a bit of a *nix newbie is there any other command to run it than:
/usr/local/bin/diskmnt.pl ? Maybe my path needs updating?

3) I would like to use this ( or something like it ) to unmount one of my main drive's three partitions. Is that possible? Currently when I run it, it unmounts both of the non-running partitions.

Thanks for your time and help in these matters.
