Get exit status, STDOUT and STDERR of a command

[topub]

Hi there,

searched faq's and google, but couldn't find a complete solution. so here I post my question.
any ideas are appreciated.

I need some way to run a OS command and get
1: exit status
2: STDOUT
3: STDERR
in three different variables.

I use open3 to run a command:

open3(gensym, \*CATCHOUT, ">&CATCHERR", $cmd);

I could get STDOUT And STDERR, but how to get exit status.
$?, didnt work.

any ideas.....
thanks,
_UB

I think system() returns the exit status...

thanks Paul.
System does return exit status, but not the other two. I want 3 (STDOUT, STDERR, exit status) in three different variables.

thanks

You could write a little subroutine to execute the command. The subroutine could work by using system() to execute the command and redirect both outputs to temporary files, then read both files and return the standard output, error output, and exit code.
