perl backticks: can't redirect output.
Hi everyone. This is a bit of a perl/linux mixed question. I am trying to redirect STDOUT of chsh by using the following line of perl code.

Code:
system ("chsh -s /sbin/nologin $testing[0] 1>/dev/null");

This should redirect STDOUT to /dev/null but it won't do that for some odd reason. Any ideas or suggestions? Thanks in advance.

Other info:
The $testing[0] is part of an array that contains the name of the account that needs its shell changed to /sbin/nologin.

nologin

NOLOGIN(5)						      BSD File Formats Manual							NOLOGIN(5)

NAME

     nologin -- disallow logins

DESCRIPTION

     Programs such as login(1) disallow logins if the nologin file exists.  The programs display the contents of nologin to the user if possible
     and interrupt the login sequence.	This makes it simple to temporarily prevent incoming logins systemwide.

     To disable logins on a per-account basis, investigate nologin(8).

SECURITY

     The nologin file is ignored for user root by default.

IMPLEMENTATION NOTES

     The nologin feature is implemented through login.conf(5), which allows to change the pathname of the file and to extend the list of users
     exempt from temporary login restriction.

     PAM-aware programs can be selectively configured to respect nologin using the pam_nologin(8) module via pam.conf(5).

     The nologin file will be removed at system boot if it resides in /var/run and cleanvar_enable is set to ``YES'' in rc.conf(5), which is
     default.  Therefore system reboot can effectively re-enable logins.

FILES

     /var/run/nologin  default location of nologin

SEE ALSO

     login(1), login.conf(5), pam.conf(5), rc.conf(5), nologin(8), pam_nologin(8), shutdown(8)
