Hey guys,
I'm trying to echo my password into some commands inside of a bash script.
But I think I'm going about it incorrectly.
Here's the top part of my script:
#!/bin/bash
pub="~/.ssh/id_rsa.pub"
dps_pass="my_pass"
ssh="/usr/bin/ssh"
scp="/usr/bin/scp"
for i in 10.10.10.2{5,6}
do
echo "xfring key up"
echo $dps_pass | $scp $PUB digitalplatform@$i:
And here's how it executes:
#bash -x deploy_key.sh
+ pub='~/.ssh/id_rsa.pub'
+ dps_pass='nbcuV01P!'
+ ssh=/usr/bin/ssh
+ scp=/usr/bin/scp
+ for i in 10.10.10.2{5.6}
+ echo 'xfring key up'
xfring key up
+ echo 'my_pass'
+ /usr/bin/scp /Users/my_user/.ssh/id_rsa.pub digitalplatform at 10.10.10.25:
Password:
Can someone please let me know where I'm going wrong?
Thanks
Tim

I'd also suggest you change your password(s) based on the <removed> line above ... from your original email. if you really want to do something like this, I'd suggest expect as the scripting language. -- public gpg key id: AE60F64C
What are you trying to do? Copy your public key out to use it for future authentication? Use ssh-copy-id to set it up the first time? Or look at the package sshpass.

Generate and use a public/private keypair instead and your script will then be able to connect without prompting for a password. Peter

That's exactly what I'm doing. Copying up my public key so that later in the script (which I didn't show, no need to I think) is to cat the public key into place and make sure there are proper permissions etc on the .ssh directory on the remote machine. But Eero and other are right.. I'll be much better off using expect to get this type of work done. It's jut that I'm more familiar with bash so I thought that there might be a good way to do it with that also.
