expect script pushing ssh keys w/ tar extract
ok, I'm new to the forum and I did a few searches and didn't find much on this so here goes.
I have a ksh I use to call an expect script that opens a ssh session and then extracts a tar file. The tar file has my prefered .profile and my ssh keys. I want to run this script 1 time on new servers and then have passwordless ssh setup.

from the command line on the source host this command does do the usual prompting for pw but once done the ssh keys are in place and future ssh connections are key based and passwordless....

ssh -q targethost 'tar xf -' </path/to/sshcfg.tar

the tar resides on the source server

but with the similar line is a expect script the tar is not found (likely looking on the target

spawn ssh -q targethost 'tar xf -' </path/to/sshcfg.tar


anyone have any thoughts ?

I don't think expect is really a proper shell, so doesn't do redirections like that.

You can always just run a proper shell to do it for you. I'm not 100% sure I have the quotes the way expect wants them, but you'd do something like this:
Code:
spawn sh -c "ssh -q targethost 'tar xf -' </path/to/sshcfg.tar"
