I have a system command like this : 

```
unix_command "@output_file path_to_file" 

```

Now when I try `exec` or `system` commands in a perl script I get this error : 

> 
> Getting a string when expecting an operator.

Can you please help me how to do it in Perl.

Appreciate your help.

Thanks a ton!
