Need to run consecutive commands on different host

[bgreen]

Hi,

I need to run consecutive commands on a differnt host. I can use rsh but that only executes one command at a time.

in host1:

rsh <host2> command1
command2
command3
...

is there a way to run the command consecutivly <host2> then going back to <host1>?

Hi,
You can run
rsh host2 command&

rsh works only if you want to run one command at a time. This will not work for what I need to do. I have to set some environment variables and then run a command. Therefore I need to stay on the particular host.

Can you place a script on host2 that sets the variables and executes your command?

Also, you might try adding the environmental variables to your command on host1, like:

rsh host2 "TZ=GMT date"

I don't run rsh, for security reasons, but that syntax works with ssh.

I have tried using rsh to run a script on host2 but ideally I would like to have it on the host1

rsh host2 abc.ksh

bgreen: one hacky method would be creating (storing) the script on host1, and when you need to run it then

rcp abc.sh host2:abc.sh
rsh host2:abc.sh

Well, this is not so pretty...

Or simply you can enumerate your commands between apostrofs, delimited by semicolons, like this:

rsh host2 ' echo first comman ; date ; echo I am the third '

but this way the number of commands is limited by the shell, as it has maximum command length.

AND FINALLY, oh yeah, I have found it You can simply run a ksh on the remote host (host2) and have its standard input open from host1

host1# cat scrip1_on_host1.sh | rsh host2 ksh
