Tools ssh and for loop
Hi all,

I am facing an issue while trying to access a for loop variable inside ssh. Can anyone please help me with what this issue is, the following is the code that I have ->

Code:
IMPL_LOG_FOLDERS=(transaction_logs invalid_transaction_logs)
 
sshg3 ftp_id@boxname << EOS
 
for log_folder in ${IMPL_LOG_FOLDERS[@]}
do
echo "my $log_folder ";
 
done
EOS

The $log_folder always prints blank. Now the script prints something like this ->

Code:
Last login: Tue May 10 2011 15:47:17 -0400 from boxname 
my 
my

This shows that the for loop is executing twice and hence it is able to read that variable IMPL_LOG_FOLDERS, what I am not understanding is why the varible log_folder can not be read from inside the for loop.

Any help regarding this will be greatly appreciated.

ssh-copy-id

SSH-COPY-ID(1)						      General Commands Manual						    SSH-COPY-ID(1)

NAME

       ssh-copy-id - install your public key in a remote machine's authorized_keys

SYNOPSIS

       ssh-copy-id [-i [identity_file]] [user@]machine

DESCRIPTION

       ssh-copy-id  is	a script that uses ssh to log into a remote machine and append the indicated identity file to that machine's ~/.ssh/autho-
       rized_keys file.

       If the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used, regardless of whether there are any keys in  your
       ssh-agent.  Otherwise, if this:

	     ssh-add -L

       provides any output, it uses that in preference to the identity file.

       If  the -i option is used, or the ssh-add produced no output, then it uses the contents of the identity file.  Once it has one or more fin-
       gerprints (by whatever means) it uses ssh to append them to ~/.ssh/authorized_keys on the remote machine (creating the file, and directory,
       if necessary.)

NOTES

       This program does not modify the permissions of any pre-existing files or directories. Therefore, if the remote sshd has StrictModes set in
       its configuration, then the user's home, ~/.ssh folder, and ~/.ssh/authorized_keys file may need to have group writability  disabled  manu-
       ally, e.g. via

	     chmod go-w ~ ~/.ssh ~/.ssh/authorized_keys

       on the remote machine.
