     I was trying to fire up an old backup of an executable I wrote:  
'ls' shows the current version and the backup:

...
-rwxr-xr-x 1 30152 2016-12-17/12:18:46 movemouse,1*
-rwxr-xr-x 1 10544 2016-12-17/12:57:53 movemouse*
...

     However zsh doesn't want to run it tho both are executable:

$ movemouse,1
zsh: command not found: movemouse,1

     Current directory is on my path:

PATH=".:/aWorking/Zsh/System:/aWorking/Bin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

     So current directory should be searched.  I can't figure out why 
zsh isn't finding it.  The recent version 'movemouse' is found fine.  
Copying 'movemouse,1' to another name somewhere else on the path made no 
difference.  But there is this:

movemouse,1:
CONTENT: EXECUTABLE BINARY application/x-executable; charset=binary:

movemouse:
CONTENT: EXECUTABLE LIBRARY application/x-sharedlib; charset=binary:

     Is that the issue?  Can anything obvious be done?  Do I need to 
rebuild 'movemouse,1'?  Yet zsh should find it anyway, no?

     Trying:

$exec ./movemouse,1

     crashed the terminal as did:

$exec ./movemouse

I think that executable's interpreter couldn't be found.

In case of native executable (i.e not a script), its linked libc couldn't be found. Please check with `ldd'

You can also try running it with plain ./movemouse,1 (instead of exec
./movemouse,1). It won't run but at least it'll demonstrate that PATH
is a red herring, and you'll be able to read the error message as you
won't be sacrificing your shell in the process.

7 /aWorking/C/Movemouse 2 $ ldd movemouse,1
     not a dynamic executable

... so that seems like a downer, even tho it is described as an 
executable binary.  So zsh 'found' it but couldn't execute it? Makes me 
think that the message should reflect that:

zsh: command found but not executable: movemouse,1

Thanks Dahn

7 /aWorking/C/Movemouse 5 $ ./movemouse,1
zsh: no such file or directory: ./movemouse,1

... so it really acts as tho the file isn't there, rather than it not 
being actually executable.

> instead of exec
That was just a shot in the dark, I thought it might reveal something.
