We have a Perl script that runs a remote shell to check for the
existence of a file on a remote system. When run in the foreground it
is fine. When run in the background (i.e. nohup, nohup with &, &, an
"atjob", or a cronjob) in hangs and never completes.

The goodies
Compaq (DEC) Alpha
Tru64 (OSF1) v4.0E
Perl v5.60
Has anyone seen this and enlighten us to correct this problem. We are
all novices at Perl at this time so please be patient.
Thanks

IIRC, this is a rsh issue, not a perl issue. Specifically, if no input
is desired you should redirect the input of rsh to /dev/null using the
-n option. See 'man rsh'.
