I just need the right syntax. I am trying to setup a bash script to copy
everything from one directory to another.
This works:
scp backup@abc-it1:/backup/. .
but the issue is it asks for a password.
This is what I've come up with (it's not working).
Any ideas on what I'm missing?
#!/bin/bash
export userpw=****
scp backup@abc-it1:/backup/. .<<-EOS
user $userpw
quit
EOS
You could try the -B option
but the best method is to create use ssh-keygen to create public keys
without passphrases on each machine. Copy the generated .pub key to the
backup@:~/.ssh folder of each machine as authorized_keys. Then ssh, scp
and rsync -e "ssh " (over ssh) won't ask for passwords or passphrases.
man scp, ssh, ssh-keygen
noi@siam :~> ls -l .ssh
total 20
-rw-r--r-- 1 noi users 402 2006-03-29 23:17 authorized_keys
-rw------- 1 noi users 1655 2005-07-02 18:41 config
