Hi Monks-

I can't explain this and need guidance from wiser minds - please help.

Here’s how to reproduce:

1.) Setup ssh public/private keys so that this unix shell command works without you having to enter a password:

$ ssh usr@remotehost date

2.) Run these command from your unix shell prompt - why does one FAIL (ask for password), while others don’t? 

$ perl -e 'system("ssh usr\@remotehost date”)’            # works
$ perl -e 'system("ssh -l usr remotehost date")’         # works
$ perl -e 'system("ssh", "usr\@remotehost", "date”)’        # works
$ perl -e 'system("ssh", "-l usr", "remotehost", "date”)’    # FAILS

You can replace system with exec and get the same result.

Thanks
