Hi. I'm calling a program with backticks from my perl script so I can get both the output text and exit code. Most of the called programs are bash or perl scripts. Occasionally a called program will be a compiled binary. Obviously, if the program was compiled on a different platform, it'll fail and throw an error to STDERR. Example, running perl script on Solaris trying to execute a binary compiled on linux.

Is there a way to test, up front, if the program I'm calling was compiled for the this platform? I'd like to just skip the program call if I can tell it won't work

The call returns a -1, but still throws the error. I tried redirecting STDERR to /dev/null, but then I no longer receive the -1.

Code: 

$text = `$command 2> /dev/null`;
$retCode = $?;

Thanks very much, Rick
