rsh breaking me out of loop

Hey all

I have two scripts, one script containing the guts of my code.

The other simply loops through a list, calling the other script on each iteration.

Problem is when I add the line

`/usr/bin/rsh -l root $HOSTNAME ""`

to my main script, the loop never seems to exectute any more items.

The scripts are very simple and I do not know what this rsh could be doing to cause my script to stop looping. Some funky shell goings on that I don't know about.

Adding the & at the end of this line stops the problem but that is undesirable.

Anyone?
Mark

NAME
rcp -- copy file to and from remote machines SYNOPSIS
rcp [-45FKpxz] [-P port] file1 file2 rcp [-45FKprxz] [-P port] file... directory DESCRIPTION
rcp copies files between machines. Each file argument is either a remote file name of the form ``rname@rhost:path'' or a local file (contain- ing no colon or with a slash before the first colon). Supported options: -4, -5, -K, -F, -x, -z These options are passed on to rsh(1). -P port This will pass the option -p port to rsh(1). -p Preserve file permissions. -r Copy source directories recursively. DIAGNOSTICS
rcp is implemented as a protocol on top of rsh(1), and thus requires a working rsh. If you intend to use Kerberos authentication, rsh needs to be Kerberos aware, else you may see more or less strange errors, such as "login incorrect", or "lost connection". HISTORY
The rcp utility first appeared in 4.2BSD. This version is derived from 4.3BSD-Reno. HEIMDAL
