Hello,

 For mount command, this command is not in my logic... I've tried and
tried again, alwais displaied the help... and unable to have it
correctly... argh... and about rename the file, when I type
pbcompiler
or
pbcompiler.exe
I read
command not found
and when I type
./pbcompiler.exe I can read
./pbcompiler: cannot execute binary file.
Now, the permissions for this file after rename it are
- - -rwxr-xr-x
if I understand, I can't read it... ?
Sory for thes question, which maybe are stupids.

Thanks in advance for help,

Patrick
