How to switch vm's

I need to go back to the 3.10-4 vm to do some profiling.  I have two
VM's installed on my Ubuntu server linux box; 3.10-4 and the new
4.0.3-2202.

Before, I used to just have a soft-link named /usr/local/bin/squeak
pointing to /usr/local/lib/squeak/3.10-4/squeak, and that is how I
would switch VM's; by repointing the soft link.

However, the new vm creates a binary file named /usr/local/bin/squeak
which, performs some Linux magic of which I am not familiar.

To attempt to switch back to the old vm, I renamed
/usr/local/bin/squeak to /usr/local/bin/squeak.renamed and
/usr/local/bin/squeak.sh to /usr/local/bin/squeak.sh.renamed.

BTW, what is squeak.sh?

I then created a softlink to the old executable:

  ln -s ../lib/squeak/3.10-4/squeak squeak

Unfortunately, when trying to launch the vm:

  squeak -version

I get:

  SQUEAK_ENCODING='UTF8'
  SQUEAK_PATHENC='UTF8'
  +exec: 1: : Permission denied

I really need to switch VM's (temporarily).  Any assistance is greatly
appreciated.

Forgot to mention, I have execute permissions on both the softlink and
the file it points to..

3.10-4 will give you different results than the closure vms.

That's a shell script, not a binary. The binary is squeakvm.

It's a script for starting squeak from GUI's:
"Launch squeak from a menu, prompting for and/or installing an image"

That looks like the output of the shell script of recent vms.

Why don't you use absolute path?
/usr/local/lib/squeak/3.10-4/squeak -your-options your.image

3.10 vms had hard-coded paths that made it difficult for non-root users to try
out squeak. The newer versions (3.11+) use a script squeak to detect and
launch from any directory. i.e. if you unzip the tar.gz into $HOME/squeak/
   $HOME/squeak/Squeak-4*/bin/squeak <imagefile>

will do the right magic env settings and command line parameters to launch
squeak. The bin/squeak.sh is for interactive launches. It throws up a native
file selection dialog so you can choose the image path.

You can use /usr/local/bin/squeak to launch 3.10 and
$HOME/squeak/Squeak-4.0*/bin/squeak to try out newer version.

HTH .. Subbu

Ah, thanks..
