SSH in batch mode and File-Handles in a loop
Hi all
I try to execute SSH commands on several hosts in a while-loop.

There seems to be a problem with file-handle, first cycle works correct but no other one will follow due to the while condition is false even that there are many more host entries (lines) in all_hosts.dat.

#!/usr/bin/ksh
exec 0<all_hosts.dat
while read line
do
echo "...executing on host :" $line
ssh $line 'ls -la /tmp' # execution aborts after the first cycle
###pwd | ssh $line 'ls -la /tmp' # continues for each entry of all_hosts.dat
done # <all_hosts.dat
#

Any clue?
Any pointer to explaining tutorials about file handles?

DESCRIPTION

       bssh/bvnc/bshell  browses  for  SSH/VNC	servers  on  the  local  network, shows them in a GUI for the user to select one and finally calls

       If the binary is called as bssh only ssh servers will be shown. If the binary is called as bvnc only VNC servers  will  be  shown.  If  the
       binary is called as bshell both VNC and SSH servers are shown.

       -v | --vnc
	      Browse for VNC servers (and only VNC servers) regardless under which name the binary is called.

       -S | --shell
	      Browse for both VNC and SSH servers regardless under which name the binary is called.

       -d | --domain= DOMAIN
	      Browse in the specified domain. If omitted bssh/bvnc/bshell will browse in the default browsing domain (usually .local)
