By default, the shell command is launched in background. You must add the WAIT 
keyword at the end of the command - see the documentation.

Because the file may exist, but the ls command didn't finish to fill it.

You should read the man page of bash ;-)
& does not concatenate shell commands, it launches them in background.
If you do "command1 & command2 & command3", you launch simultaneously 
command1, command2 and command3, and waits only for the end of the command3 
command.

Try to use ";" instead of "&".
